摘　　要：A new diamine, disodium 4, 4-di(4-aminophenoxy)-3, 3-disulfonate-1, 1- diphenyl- ketone, was prepared from the nucleophilic substitution of disodium 4, 4- difluoro-3, 3-di- sulfonate-1, 1-diphenylketone and p-aminophenol. Polymerization of this diamine and 4, 4-diamino-1, 1- diphenyl ether with 3, 3, 4, 4-tetracarboxyl dianhydride-1, 1- diphenyl ketone gave ion-exchange copolyimide. The new diamine and its polyimide were characterized with 1H-NMR and FT-IR.A new diamine, disodium 4, 4-di(4-aminophenoxy)-3, 3-disulfonate-1, 1- diphenyl- ketone, was prepared from the nucleophilic substitution of disodium 4, 4- difluoro-3, 3-di- sulfonate-1, 1-diphenylketone and p-aminophenol.
