摘　　要：Nd(C_8H_(11))Cl_2·3THF与不同烷基铝〔Et_3Al,i-Bu_3Al,HAl(i-Bu_2)〕组成的催化体系可催化丁二烯聚合。实验结果表明,催化剂活性取决于所用的烷基铝、铝钕比和催化剂用量,而溶剂对催化活性影响不大。聚合物的微观结构则不受烷基铝种类、溶剂、铬钕比和催化剂用量的影响,均可得到高顺式(97—98％)聚丁二烯。Butadiene was polymerized with the catalyst system composed of Nd(C_8H_(11))Cl_2·3THFand aluminium alkyls. The experimental results show that the activity of the catalysts de-pends on the aluminium alkyls used,the ratio of Al/Nd and the concentration of the catalysts,but not remarkably affected by solvents. The microstruture of the polymers was independent of the polymerization conditions used.Polybutadicne,with high cis-1,4 content (97-98%) was obtained.
