【Abstract】 A novel poly (aryl ether ketone) (PPEK) containing phthalazinone and 1,4 naphthylene was prepared by the nucleophilic displacement reaction of 4 (4 hydroxyphenyl) (2N) phthalazin 1 one with 1 chloro 4 (4 chlorobenzoyl) naphthalene. The polymer was characterized with FT IR, 1H NMR, DSC, TG and WAXD. It has been proved that PPNEK was a amorphous plastics with high glass transition temperature ( T g=287 ℃) and good thermal stability. It was soluble in some solvents.更多还原
