| Abstract: | Polyether ketone ketones containing diphenyl group(DPEKKs) were prepared by Friedel Crafts acylation polycondensation of diphenyl(DP), diphenyl ether(DPE), terephthaloyl chloride(TPC) and isophthaloyl chloride(IPC). The prepared copolymers were characterized by infrared spectroscopy, X ray diffraction, solvent resistant test, differential scanning calorimetry and thermogravimetry. The melting temperatures and glass transition temperature of the DPEKKs are higher than that of the PEKK when the mole ratios of diphenyl to diphenyl ether are between 5/95 to 50/50. The crystallinities of the DPEKKs increase with increasing of mole ratios of diphenyl to diphenyl ether and the decomposing temperature of the DPEKKs are higher than that of the PEKK. The DPEKKs have excellent chemical resistant property and possess higher service temperatures than the PEKK. |
