摘　　要：研究了乙丙橡胶（EPDM）生胶的加工性能和物理机械性能。结果表明：即使较高门尼粘度,只要具有宽相对分子质量分布的EPDM也能体现优异的生胶包辊性能;长时间的生胶塑炼仅在前5min对高门尼牌号EPDM的门尼粘度有一定影响;不填充补强剂的EPDM生胶拉伸强度仅有1～3MPa,没有使用价值。Raw rubber processability and physical mechanical properties of EPDM were studied. The results showed that even if the Mooney viscosity is higher,it can reflect the outstanding raw rub- ber roll package performance as long as its wide molecular weight distribution ; it had effects on Moo- ney viscosity of higher Mooney viscosity grade only in the first 5 minutes of long time plastication; EP- DM raw rubber tensile strength was only 1～2 MPa if not filling reinforcing agent,it was useless.
