Abstract

Three different poly(ether-amide imide)s[PEAI], containing benzophenone, bisphenol A and suifone units, have been syllthesized from corresponding poly(ether-amide-allelic aci(B) s[PEAAA] by means of cyclodehydration which were obtained from the reaction of trimellitic anhydride chloride(TMAC) with 4,4'-bis (m-aminophenoxy) benzophenone, 2,2-bis(4-(m-aminophenoxy) phenyl)propane and 4,4'-bis(m-aminophenoxy) diphenyl sulfone, respectively. It hat bell revealed that all PEAI's are thermally stable (temperatures at 5% weight loss are 480-504℃) and have the glass transition temperatures(in the vicinity of 200℃) suitable to be processed by conventional extrusion or injection molding. And also they show the good solubility to polar organic solvents, such as pyridine, N,N-dimethyl formamide and dimethylsulfoxide.
