摘　　要：The blends of HQ PPEK, prepared by polymerization of 4 (4 hydroxyphenyl) 1 phthalazone(DHPZ) and hydroquinone(HQ)(1∶1 molar ratio) with 4,4 diflourodiphenylketone and polycarbonate(PC) through coprecipitation in chloroform solution. The miscibility of the blends was characterized by ternary solution methods and DSC. The results indicated that the blends were immiscible or partially miscible. The rheological properties of the blends were studied by capillary rheometer. The results show that the melt blends are psedoplastic fluids, the die swelling ratios decrease and the non Newtonian index increases with increase in the weight content of PC in the blends and the blends viscosity curves negatively does not follow the single additivity rule.The blends of HQ PPEK, prepared by polymerization of 4 (4 hydroxyphenyl) 1 phthalazone(DHPZ) and hydroquinone(HQ)(1∶1 molar ratio) with 4,4 diflourodiphenylketone and polycarbonate(PC) through coprecipitation in chloroform solution.
