摘　　要：研究了在Ni(naph)2-Al(i-Bu)3-BF3.OEt2(简称Ni-A1-B)体系中添加亚磷酸酯类配体(P)对丁二烯聚合动力学的影响。结果表明,含P体系在聚合反应初期属快引发、逐步增长、无链终止的聚合反应体系;聚合速率对单体浓度呈一级动力学关系;表观活化能为Ea=36.66 kJ/mol。Polymeric kinetics of butadiene initiated with nickel-base catalyst,Ni（naph）2-Al（i-Bu）3-BF3·OEt,involving a certain phosphite ester ligand was investigated.The results showed that the character of this polymerization rate was rapid initiation rate,step propagation and no termination at the initial reaction stage of this polymerization.The rate of polymeriztion was found to be first order with respect to monomer concentration and the apparent activation energy was 36.66kJ/mol.
