| 摘 要： | 以溶液共沉淀的方法制备了含二氮杂萘联本结构的聚芳醚砜酮（PPESK）。聚苯乙烯（PS）共混物，用毛细管流变仪测定了共混物的流为性能。结果表明，在本实验条件下，PPESK／PS共混物熔体属假塑性非牛顿汉体，其熔体粘度随PS含量的增加、温度的升高、剪切速率的增大而下降。PS的加入有利于改善PPESK的熔融加工流动性。

| Abstract: | Blends of poly(phthalazinone ether ketone sulfone)(PPESK)and polystyrene(PS) were prepared by solution coprecipatation. Rheological behaviors of PPESK/PS blends were studied by AG 2000A capillary rheometer. Results showed that the blends were pseudoplastic and non Newtonian. Melt viscosity of the blends decreased with the increase of PS content,temperature and shear rate. Flowability of PPESK may be improved greatly by the addition of PS. |
