| 摘 要： | 1976年F.Dawans在研究丁二烯定向聚合时,曾引入三氟乙酸氯化镍类型的乙醚络合物,对聚合机理作了令人满意的解释并已得到实际应用。但迄今为止,稀土催化剂作为定向聚合催化剂,在三烷基铝低用量条件下,均系非均相的三元体系。这在理论研究和实际应用上都存在一定困难。

| Abstract: | A new type of lanthanide complex was synthesized. The analytical results indicate that this compound is (CF2COO)2NdCl-20Et2. A binary catalyst system based on this complex combined with AlR2 can initiate polymerization of butadiene and isoprene to give homopolymer of high cis-1, 4 content. Light scattering method indicates that both the states of the aged catalyst solution and of polymerization solution are homogeneous system. |
