introduction polyetherimine prepared from bisphenol a diether dianhydride (BPADA) monomer is a kind of fusible polyimide, which not only maintains various excellent properties of polyimide, but also has the processing properties of general plastic plastics, and is cheap, suitable for preparing thin-walled products and products with complex structures.
application bisphenol a diether dianhydride can be used as the main raw material for the production of polyimide products and their composites.
synthesis method bisphenol a diether dianhydride was synthesized from 4-chloro phthalic anhydride and bisphenol a. It mainly includes the following steps:(1) imidization of chlorophenyl anhydride to synthesize N-phenyl-4-chloro phthalimide,(2) synthesis of bisphenol A disodium salt,(3) Nucleophilic substitution reaction in dipolar aprotic solvent,(4) hydrolysis to obtain bisphenol A diether tetraacid, and (5) dehydration to obtain bisphenol A diether dianhydride.
use is the main raw material for the production of polyimide products and their composites
