摘　　要：采用巯基化合物作为聚氯乙稀和三元乙丙橡胶的共混体系的偶联剂。用机械共混法制样,研究了偶联剂对PVC/EPDM体系的力学性能及形态结构的影响。证实了共混体系有两相存在,并在此基础上提出了含有偶联剂的共混体系的增韧机理。With the aid of adding some mercapto compound into PVC/EPDM blends as a coupling agent, the sample blends are prepared by mechanical blending, and the influences of the coupling agent on the mechanical properties and the miscrostructure of blends are studied.It is proved t at there exist two phases, on the basis of which a loughness mechanism of the blends with a coupling agent added is proposed.
