摘　　要：借助于剖分式双螺杆挤出机对PP/EPDM共混体系的熔融混合过程进行了沿程取样研究。实验表明 ,耗散混合熔融是PP/EPDM挤出过程中主要的熔融机理 ;混合与熔融同时发生 ;混合包含两种机理 。With clam shell twin screw extruder, the melting mechanism and mixing mechanism of PP/EPDM along the screw were investigated. It showed that dissipative mix melting was the main melting mechanism. Mixing and melting occurred simultaneously. There were two mixing mechanisms: Macor mixing Mechanism and Micro melting Mechanism.
