The article was appeared in 《Polymer International》. They have made some progress in their research.Name: 5,5′-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))bis(isobenzofuran-1,3-dione) The article mentions the following:

New crosslinked polyamides were successfully produced from the condensation of pre-synthesized monomer, 5-(2,2,2-trifluoroacetamido)isophthaloylchloride (TFAIAC) and diamines at low temperature These polyamides were used as promising metal-chelating adsorbents due to the presence of O and N donor sites on the crosslinked polyamides. For this purpose, trifluoroacetic anhydride was used to protect the amino group of 5-aminoisophthalic acid, thus generating 5-(2,2,2-trifluoroacetamido)isophthalic acid (TFAIA). TFAIA was converted into TFAIAC using oxalyl chloride, which was exploited as a suitable monomer for the synthesis of aromatic polyamides. Amino groups were then set free under basic conditions and the crosslinking was carried out through amino groups present on the polyamide chains with different dianhydrides, isophthaloyl chloride and 2,5-thiophenedicarboxaldehyde. The synthesis of monomers and polymers was confirmed by FTIR, 1H and 13C NMR spectroscopy and molar masses were measured by gel permeation chromatog. The crosslinked macromols. were found to possess enough chain alignment as depicted by their XRD patterns. The thermal stability of the crosslinked polyamides was increased as their decomposition temperatures were improved from 420 to 619 °C. Metal ion uptake was scrutinized through at. absorption spectroscopy with 83%-85% adsorption capacity at optimized parameters. The mechanism of adsorption was further investigated through the Freundlich and Langmuir adsorption isotherms.

The article contains the following contents:

Demands of increased energy d. and high-safety of lithium-ion and lithium metal batteries are growing for advanced electronics, elec. vehicles and energy storage systems. Nickel-rich layered oxides such as LiNi0.8Co0.1Mn0.1O2 (NCM811) are appealing as promising high-capacity cathode materials. Their reversible capacity increases further by charging to higher voltages than conventional 4.2 V, which is however difficult to make because of unstable cathode-electrolyte interface and structural degradation Herein, we report the combination of NCM811 cathode active material with non-aqueous functional polyimide binder to imparts enhanced thermal stability and highly stable interface originating from in situ building-up of surface protective polyimide layer at cathode through monodentate metal-carboxylate chem. bonds during slurry preparation, which permits to charge to 4.4 V despite in com. electrolyte without any additive. This unique active material-binder combination not only suppresses metal-dissolution and cathode degradation and produces increased reversible capacity higher than 200 mAh g-1 but also provides unprecedented non-flammable characteristics contrary to the case of conventional binder, enabling a stable operation of higher energy and safer batteries.

The article was appeared in 《European Polymer Journal》. They have made some progress in their research.Recommanded Product: 38103-06-9 The article mentions the following:

One kind of the leading polymers applied in microelectronic packaging is polyimide (PI)-tethered polyhedral oligomeric silsesquioxane (POSS) hybrids. However, a well-known problem is that PI-POSS hybrids usually suffer from the serious thermal expansion at elevated temperature, leading to deteriorated reliability in electronic devices. In this work, a series of PI-POSS hybrids is successfully fabricated using aminopropylisobutyl-POSS as a reactive filler, and then the phenolic hydroxyl groups on side chains of hybrids react with terephthaloyl chloride at room temperature to form a crosslinked network. The well-designed crosslinked network suppresses the thermal expansion and improves the dielec. properties of hybrids together with POSS. As an example, after 24 h of crosslinking reaction, the coefficient of thermal expansion of the crosslinked hybrid with 14.6 wt% POSS (CPIH-2-24H) is 24 ppm/K, revealing a 59% reduction against the unmodified PI (82 ppm/K). Meanwhile, the dielec. constant and loss of CPIH-2-24H are decreased by ∼27% (2.68 vs. 3.68) and ∼72% (0.007 vs. 0.025), resp., compared with the corresponding values for the unmodified PI. These data indicate that the resultant crosslinked PI-POSS hybrids may be used as microelectronic packaging materials, and the work provides a feasible approach to restrict the thermal expansion of PI-POSS hybrids by room-temperature chem. crosslinking.

The research results were published in《Polymer Chemistry》 in 2020.Electric Literature of C31H20O8 The article conveys some information:

Herein we have synthesized telechelic sulfonated polyetherimides (PEIs) with a series of metal cations, including alkali metal cations (Li+, Na+, and K+) and alk. earth metal cations (Mg2+, Ca2+, and Sr2+). By comparing the metal sulfonated PEIs with a noncharged analog phenyl-terminated PEI, we have systematically investigated how the metal cations affect the thermal, mech., and rheol. properties of PEIs. PEIs with alk. earth metal cations showed higher thermal degradation temperatures than those with alkali metal cations. All sulfonated PEIs showed lower thermal degradation temperatures than noncharged PEIs. All metal cations except K+ and Sr2+ increased the glass transition temperatures of sulfonated PEIs. Most metal (except K and Sr) sulfonated PEIs possessed good film formability when the mol. weight was above 10 kDa. Due to their large cation sizes, the K and Sr sulfonated PEIs exhibited reduced glass transition temperatures and inferior film formability. Alkali metal sulfonated PEIs showed high thermo-oxidative stability, but none of the alk. earth metal sulfonated PEIs exhibited good thermo-oxidative stability. The rheol. time-temperature superposition revealed that the interaction strength between the sulfonate anions and the alkali metal cations decreased as the cation size increased in the sequence of Li+, Na+, and K+. This study provides a guideline for synthesizing metal sulfonated PEIs and other metal sulfonated polymers with tailored thermal, mech., and rheol. properties.

In the paper, we demonstrate a series of azobenzene polyimides with azomoieties located in the main chain for potential applications as membranes for controlled gas separation Since azobenzene derivatives can exist in two forms, i.e., thermodynamically stable trans and photoinduced cis, both isomers can be utilized for membrane preparation The long term stability of the cis form is a precondition for such an application. Thus, the effect of polymer structure on the stability of cis-trans isomerization process in polymer films was investigated. The prepared azopolymers exhibited high stability of cis isomers and the return cis-trans reaction was not completed during 7 days after switching off the excitation light (405 nm). The stability of the cis-trans isomerization was discussed in the context of the fragility parameter. To the best of our knowledge, it is the first time when the main chain azopolymer was tested as a membrane for the gas separation Two types of azomembranes, i.e., bearing azobenzene derivatives as trans, and cis isomers and a reference membrane without azochromophore were prepared Our investigations showed that the presence of trans-azomoieties increases the permeability of the gases (N2, O2, He and CO2) in comparison to the reference polyimide and that the permeability increase is not accompanied by any losses of the selectivity.5,5′-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))bis(isobenzofuran-1,3-dione) (cas: 38103-06-9) were involved in the experimental procedure.

Application of 38103-06-9《Polyimide Aerogel Fibers with Superior Flame Resistance, Strength, Hydrophobicity, and Flexibility Made via a Universal Sol-Gel Confined Transition Strategy》 was published in 2021. The authors were Li, Xin;Dong, Guoqing;Liu, Zengwei;Zhang, Xuetong, and the article was included in《ACS Nano》. The author mentioned the following in the article:

Aerogel fibers with ultrahigh porosity, large sp. surface area, and ultralow d. have shown increasing interest due to being considered as the next generation thermal insulation fibers. However, it is still a great challenge to fabricate arbitrary aerogel fibers via the traditional wet-spinning approach due to the obvious conflict between the static sol-gel transition of the aerogel bulks and the dynamic wet-spinning process of aerogel fibers. Herein, a sol-gel confined transition (SGCT) strategy was developed for fabricating various mesoporous aerogel fibers, in which the aerogel precursor solution was first driven by the surface tension into the capillary tubes, then the gel fibers were easily formed in the confined space after static sol-gel process, and finally the mesoporous aerogel fibers were obtained via the supercritical CO2 drying process. As a typical case, the polyimide (PI) aerogel fiber prepared via the SGCT approach has exhibited a large sp. surface area (up to 364 m2/g), outstanding mech. property (with elastic modulus of 123 MPa), superior hydrophobicity (with contact angle of 153°), and excellent flexibility (with curvature radius of 200μm). Therefore, the aerogel woven fabric made from PI aerogel fibers has possessed an excellent thermal insulation performance in a wide temperature window, even under the harsh environment. Besides, arbitrary kinds of aerogel fibers, including organic aerogel fibers, inorganic aerogel fibers, and organic-inorganic hybrid aerogel fibers, have been fabricated successfully, suggesting the universality of the SGCT strategy, which not only provides a way for developing aerogel fibers with different components but also plays an irreplaceable role in promoting the upgrading of the fiber fields.5,5′-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))bis(isobenzofuran-1,3-dione) (cas: 38103-06-9) were involved in the experimental procedure.

Wu, Yancheng;Ji, Jingqi;Huang, Haohao;Liu, Shumei;Zhao, Jianqing published 《Facile synthesis of acyloxy-containing fluorene-based Cardo polyimides with high optical transparency, fluorescence and low dielectric constant》. The research results were published in《Reactive & Functional Polymers》 in 2021.Recommanded Product: 38103-06-9 The article conveys some information:

A series of acyloxy-containing fluorene-based Cardo polyimides (PIs) were facilely synthesized by the post-polymerization modification based on a simple esterification of hydroxyl-containing PIs. Incorporation of acyloxy groups may reduce the packing d. of PI chains and weaken both inter- and intra-chain charge transfer complexes (CTC) formation. Accordingly, the modified PIs exhibit the improved solubility in low-boiling-point solvents and optical transparence. The optical transmittance at 400 nm (T400) of all modified PI films is significantly increased to 80.1-83.5% from 41.6-54.5% of the precursor PI films. Meanwhile, the modified PI films exhibit a bright fluorescence. The modified PIs still display the superior heat resistance with a glass transition temperature (Tg) of 301.1-390.9°C as well as admirable mech. properties with a tensile strength (TS) of 72.1-81.3 MPa. In addition, the dielec. constant (k) value at 1 MHz of the modified PI films is decreased to 2.58-2.90 from 3.95-4.48 of the precursor PI films, which is attributed to the enlarged free volume and reduced water absorption afforded by the incorporation of acyloxy groups. This work provides an efficient post-polymerization modification approach to simultaneously affording the multifunctional PI films with high Tg, high T400 and low k, probably as the potential candidates for the practical application in display and microelectronic industries.

The article was appeared in 《Polymer》. They have made some progress in their research.Application of 38103-06-9 The article mentions the following:

The design of linear high performance polyetherimides (PEIs) comprising 3,3′- and 4,4′-bisphenol-A dianhydride (bis-DA) and m-phenylene diamine (mPD) provided an opportunity to elucidate the influence of dianhydride regiochem. on thermomech. and rheol. properties. This unique pair of regioisomers allowed the tuning of the thermal and rheol. properties for high glass transition temperature polyimides for emerging engineering applications. Step-growth polycondensation enabled the production of high mol. weight PEIs for subsequent thermal and mech. anal. Monofunctional phthalic anhydride as an endcapper and monomeric stoichiometric imbalances enabled predictable number-average mol. weights ranging from 3600 to 35,400 g mol-1, as confirmed with size exclusion chromatog. coupled with light scattering detection for absolute mol. weight determination The selection of the dianhydride regioisomer influenced the weight loss profile as a function of temperature, entanglement mol. weight (Me), glass transition temperature (Tg), tensile strain-at-break, zero-shear melt viscosity, average hole-size free volume (Vh), and the plateau modulus prior to viscous flow during dynamic mech. anal. The 3,3′- PEI composition interestingly exhibited a ∼20°C higher glass transition temperature than the corresponding 4,4′- PEI analog. Moreover, melt rheol. anal. revealed a two-fold increase in Me for 3,3′- PEI, which pointed to the origin of the differences in mech. and rheol. properties as a function of PEI backbone geometry. To complete the study, the researchers used 5,5′-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))bis(isobenzofuran-1,3-dione) (cas: 38103-06-9) .

5,5′-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))bis(isobenzofuran-1,3-dione)(cas: 38103-06-9) is a diallyl based epoxy modification agent that blends with the resin to improve the mechanical property of the epoxy material.Application of 38103-06-9 It is majorly used in novalac based resins, which can be further cured with bismaleimides (BMI) for aerospace, electronics and wireless communication based applications.
