Two novel poly(ether ether ketone)s(PEEK) containing imide moiety with inherent viscosities of 0.98 dL/g and 0.61 dL/g were respectively prepared by low temperature solution polycondensation from 1,4-diphenylbenzene(DPB) with N,N'-(4,4'-diphenylmethane) bistrimelletimide diacid chloride(DCDI-M) or N,N'-(4,4'-diphenylsulfone) bistrimelletimide diacid chloride(DCDI-S).The polymers were characterized by FT-IR,1H NMR,DSC,TGA and WAXD.The results show that the polymers are amorphous.The glass transition temperatures(Tg) are 236 ℃ and 263 ℃,respectively.The onset temperatures taken at a 5% mass loss of each of the polymers in nitrogen atmosphere are all over 512 ℃.The polymers are soluble in common organic solvents such as N,N-dimethylacetamide(DMAc),N-methylpyrrolidone(NMP),cresol and chloroform at room temperature.
