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 In Synthesis of 5,5′-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))bis(isobenzofuran-1,3-dione) It is majorly used in novalac based resins, which can be further cured with bismaleimides (BMI) for aerospace, electronics and wireless communication based applications.

Jiao, Long;Du, Zhijun;Dai, Xuemin;Wang, Hanfu;Yao, Haibo;Qiu, Xuepeng published 《Multifunctional polyimide films with superheat-resistance, low coefficient of thermal expansion and fluorescence performance》 in 2022. The article was appeared in 《Polymer》. They have made some progress in their research.Application In Synthesis of 5,5′-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))bis(isobenzofuran-1,3-dione) The article mentions the following:

A series of novel aromatic polyimide (PI) films containing xanthone moiety was prepared through a two-step procedure, namely, the polymerization of 2,7-diaminoxanthone (2,7-DAX) and six aromatic anhydrides and thermal imidization. The solubility, thermal properties, dimensional stability, mech. properties, and fluorescence performance of the resulting PI films were studied extensively. The PI-1 film prepared by Pyromellitic dianhydride (PMDA)/2,7-DAX has a glass transition temperature (Tg) of more than 450°C, a coefficient of thermal expansion (CTE) of as low as 6.3 ppm K-1, 5% weight loss temperature (T5) of 608°C, a tensile strength of 164 MPa, and a tensile modulus of 5.65 GPa, resulting in potential applications in the flexible OLED field. In addition, xanthone moiety acts as a fluorophore group to provide a polymer fluorescent performance, and the maximum emission wavelength is in the range of 443-552 nm, from blue color to yellow color. And 5,5′-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))bis(isobenzofuran-1,3-dione) (cas: 38103-06-9) was used in the research process.
