PPS/PEEK melt blend prepared by melt-blending is introduced,and the influence of a dif- ferent content of PEEK and a different size of PEEK particales on the crystallization behavior of PPS in the PPS/PEEK blend is investigated by DSC.

• 采用熔融共混法制备结晶/结晶共混体系PPS/PEEK,并用差示扫描量热法研究了不同PEEK含量和不同PEEK粒径对PPS/PEEK共混物中PPS组分结晶行为的影响。
