High molecular weight copoly(ether ketone)s (PEK) based on 4-(4-hydroxyphenyl)-l-phthalazinone (DHPZ)/4,4'-thiobisphenol (TBP)/4,4'-diflourodiphenylketone (DFK) were prepared by nuclcophilic substitution polycondcnsation. The copolymers were characterized by FT-IR and ¹H-NMR. Thermal properties and solubility of copolymers were studied.
