Preparation of 2,2-bis[4-(3-aminophenoxy)phenyl]propane (3-BAPOPP) was carried out through the reducing reaction of 2,2-bis[4-(3-nitrophenoxy)phenyl]propane (3-BN-POPP) in the presence of active carbon,ferric chloride hexahydrate (FeCl 3·6H 2O) and hydrazine hydrate.The obtained monomer (3-BAPOPP) was characterized by the melting point test technology,the FT-IR technology in the solvent of N,N'-dimethylacetamide (DMAc).The novel polyamic acid (3-BAPOPP/BTDA-PAA) was polycondensed between 3-BAPOPP monomer and 3,3',4,4'-benzophenone tetracarboxylic dianhydride (BTDA)monomer at toom temperature.The PAA is further cyclodehydrated into polyimide (3-BAPOPP/BTDA-PI) in the presence of acetic anhydride and triethylamine (TEA).The properties of the PAA and the PI were also studied respectively.
