摘　　要：研究了新型钒催化剂催化乙丙共聚合规律。结果表明,催化剂浓度、n(Al)/n(V)对聚合反应速率及共聚物产量有显著的影响,而n(C3H6)/n(C2H4)、H2浓度、ENB加入量对生成共聚物结构及共聚物相对分子质量有影响。The regularity of copolymerization of ethylene-propylene with the new vanadium catalyst was studied.Results showed that the effect of catalyst concentration and n(Al)/n(V) on reaction rate and product of copolymerization of ethylene-propylene is remarkable,the effects of the ratio of monomer concentration, the amount of molecular weight adjusting agent and the amount of the third monomer on micro structure properties of polymer and molecular weight are also present.
