Abstract

Abstract: A novel poly(aryletherketone) copolymer containing phthalazinone moiety was prepared by nucleophilic substitution reaction of 4-(4-hydroxyphenyl)(2H) phthalazin1one with bis-1,4-(4-chlorobenzoyl) benzene(BCBB) and 4,4'-difluorobenzophenone(DFPK). The copolymer has been studied by FTIR, DSC, TGA and X-ray diffractometry. It is an amorphous plastics with T_g=245～254℃ and good thermal stability, and the T_gs of the copolymer were increased with decreasing of molar ratio of BCBB to DFPK. The copolymer is soluble in aprotic dipolar solvents.

Key words: poly(aryletherketone), hetero cyclic copolymer, property
