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