A series of poly(aryl ether ketone ketone)(PEKK) copolymers of high molecular weight have been synthesized at -15~25℃ by solution polycondensation of diphenyl ether(DPE), tetraphthaloyl chloride(TPC) and dibenzo-p-dioxin(ODP) using AlCl₃ as a catalyst, 1,2-dichloroethane and NMP as solvents. The copolymers have been characterrized by DSC and WAXD. The results showed that the T_g of the copolymers increase, the T_m and crytallinity decrease with increase in dibenzo-p-dioxin fragments. The copolymers still have excellent heat and solvent-resistance as pure PEKK.
