摘　　要：研究了共混时间和 5种共混方法对动态硫化EPDM(乙烯 /丙烯 /二烯共聚物 ) /PP的结晶相态结构及力学性能的影响。结果表明 ,随着共混时间的延长 ,EPDM/PP体系的力学性能先变好后变差 ,当共混时间为 5min时EPDM/PP体系的力学性能最佳 ;无论是采用哪种共混方法 ,均能形成完全硫化的弹性体相 。The effects of blending time and blending technique on crystallization morphology and mechanical pro perties of EPDM/PP were studied. The results showed that the mechanical properties of EPDM/PP increased at first, and then decreased as the blending time increased. The optimal mechanical properties of the blend were obtained when EPDM/PP was blended for 5 min, whatever blending technique was adopted, a completely vulcanized elastomeric phase was formed.EPDM/PP having different mechanical properties was yielded.
