摘要:A novel series of poly(aryl ether sulfone ketone)s (PPESKs) containing phthalazinone and biphenyl moieties were prepared by two-step nucleophilic polycondensation reaction. The (M) over bar (W) values of these copolymers were between 38,330 and 67,900. The glass transition temperatures (T-g) and 5% decomposition temperatures were ranged in 253-269 degrees C and 488-500 degrees C, respectively, The structures of these copolymers were confirmed by FT-IR and H-1 NMR. Moreover, all the resultant copolymers were amorphous determined by wide angle X-ray diffraction (WAXD). (C) 2007 Xi Gao Jian. Published by Elsevier B.V on behalf of Chinese Chemical Society.
