摘　　要：研究了聚丙烯动态硫化体系及工艺对聚丙烯复合材料力学性能及熔体强度的影响 ,结果表明 ,交联剂、交联助剂、改性剂。The influences of dynamic vulcanization composition and processes on mechanical properties of high melt strength of PP composites have been studied. The result shows that crosslinker, crosslink-assistants, modifier, feed rate and process temperature are the main affecting factors on Izod impact strength and melt strength of PP composites. High melt strength PP composites are prepared with twin-screw extruder and dynamic vulcanization technology.
