The variation of the MW and MWD of cis-polybutadiene in the course of polymerizauon catalyzed by lanthanide complex composed of triisobutyl aluminium or diisobutyl aluminium hydride was investigated by osmometry
viscometry and SEC. By analyzing the experimental data
the reasons of the appearance of bimodal MWD of lanthanide cis-polybutadiene and the possible mechanisiums of polymerization were discussed.
