Application

9,9-Bis(3,4-dicarboxyphenyl)fluorene Dianhydride, a white to almost white powder or crystalline substance, serves a crucial role in the production of polyimide monomers. With a purity of at least 98%, this compound is instrumental in developing polymers with advanced properties. Its high melting point of approximately 240°C allows it to function effectively as a catalyst for the thermal oxidation of aromatic hydrocarbons. Additionally, it acts as a crystallization and oxidizing agent in the dehydration of crystals, eventually leading to the formation of epoxy resin. Notably, it is used to prepare novel imine oligomers and thermosets, offering improved solubility in organic solvents and higher melt viscosity compared to traditional compounds. The unique cardo architecture of its imide oligomers results in superior thermal properties, including a glass transition temperature exceeding 404°C and a 5% weight-loss temperature surpassing 549°C in air. These BPAF-derived thermosets showcase excellent high-frequency dielectric properties, with a low dielectric constant and loss factor, alongside impressive mechanical properties. Thus, polymers based on this dianhydride hold great potential as matrix resins for heat-resistant structural and functional composites, meeting the demands of advanced industrial applications.
