摘　　要：研究了由过氧化二异丙苯(DCP)和助交联剂三烯丙基异氰脲酸酯(TAIC)组成的过氧化物体系对液体三元乙丙橡胶(EPDM)的交联及产物拉伸性能的影响。结果表明,液体EPDM的凝胶含量随DCP的增加无明显变化,随TAIC的增加而增加;交联产物的拉伸性能有相似的变化趋势。The effect of erosslinking agent dicumyl peroxide （DCP） and co-crosslinking agent triallyl isocyanurate（TAIC） on the cure and tensile properties of liquid ethylene propylene diene monomer （EPDM） was investigated. The results indicated that the gel content of cured liquid EPDM had variance hardly with increasing the amount of DCP,however, increased with increasing the amount of TAIC. The tensile properties of cured liquid EPDM had a similar varing trend to that of gel content with the increase of DCP or TAIC.
