A series of cross-linked polyimides (PIs) were prepared via two-step solution polycondensation from 2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride (BPADA) and 2,5-furandicarboxylic acid-based diamines, N,N’-bis(4-amino-2-(trifluoromethyl)phenyl)furan-2,5-dicarboxamide (TFFDA) and N,N’-bis(4-aminophenyl)furan-2,5-dicarboxamide (p-FDDA), followed by thermal crosslinking reaction with bismaleimide. The thermal crosslinking reaction and its mechanism were studied by FTIR spectra and model reaction anal., which showed Diels-Alder reaction between furan group and maleimide group played a main role in the thermal treatment. The properties of cross-linked PIs were characterized using dynamic mech. thermal anal., thermogravimetric analyses, tensile testing, UV-visible spectra, and wide-angle X-ray diffraction. The cross-linked polyimide film showed improved solvent-resistance, thermal and mech. properties with Tg values of 234-306°C, tensile strengths of 82-98 MPa and moduli of 2.3-3.0 GPa. 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.Related Products 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.
