A series of random copolymers composed of polyetherketoneketone (PEKK) and polyethersulfoneetherketoneketone(PESEKK) containing naphthalene ring were prepared by low temperature solution polycondensation of 4
4′- bis( β- naphthoxy) diphenylsulfone(BNODPS)
diphenylether(DPE) and terephthaloyl choride (TPC) in 1
2 dichloroethane and in the presence of AlCl 3 and NMP. Some properties of the copolymers were investigated by DSC
TG
WAXD
etc.. The results show that the T g of the copolymer is higher than that of pure PEKK
the melting temperature and the crystallinity of the copolymer decrease with increasing of PESEKK unit contents.the copolymers have good heat resistance and excellent chemical resistance.
