【摘要】 将聚丙撑碳酸酯（ＰＰＣ）与三元乙丙橡胶（ＥＰＴ）共混制成弹性体。研究了ＰＰＣ的添加量、硫化剂的种类及用量、硫化时间、硫化温度和添加炭黑对共混弹性体的物理力学性能、交联度的影响。研究发现，ＰＰＣ能与ＥＰＴ形成化学交联，加入一定量的ＰＰＣ能使ＥＰＴ弹性体的拉伸强度、断裂伸长率提高。更多还原

【Abstract】 In this paper, the blends of poly(propylene carbonate)(PPC), with ethylene propylene dienmischpolymere rubber(EPT) were prepared. The effects of PPC content, curing agent, curing temperature, curing time and adding carbon black on the mechanical properties of the blends were studied. Adding PPC can improve the mechanical properties of the blends of PPC/EPT system.更多还原
