摘　　要：研究了EPDM/PP在注射、挤出、模压等不同加工工艺过程中,改变工艺参数对其性能的影响。同时还进一步探讨了注射条件对制品结晶形态的影响。实验结果表明:在不同的工艺条件下试样的性能有很大的差别。EPDM/PP的注射成型制品显示出典型的皮芯形态,差示扫描量热法(DSC)测试证明了皮层和芯层的结晶形态有明显差别。The influence of changing processing parameters during injection, extrusion and mould pressing on properties of EPDM/PP was studied. Moreover, the crystallization morphology in the injection molding was discussed. The results showed that the specimen possessed very different properties under different processing conditions. The distinct skin-core morphology was discovered in the injection products. It was justified by differential scanning calorimetry（DSC）test.
