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.
