SYNTHESIS OF NEODYMIUM DI-TRIFLUORACETATE CHLORIDE AND ITS CATALYTIC ACTIVITY FOR POLYMERIZATION OF DIENES
二(三氟乙酸)氯化钕的合成及其对双烯聚合的催化活性

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.
