| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| 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 |
