THE BIMODAL MOLECULAR WEIGHT DISTRIBUTION OF cis-POLYBUTADIENE POLYMERIZED WITH LANTHANIDE COMPLEX CATALYSTS
The variation of the molecular weight and molecular weight distribution of cis-polybutadiene in the course of polymerization catalyzed by lanthanide complex composed of triisobutyl aluminium or diisobutyl aluminium hydride was investigated by osmometry
viscometry and size exclusion chromatography. By analyzing the experimental data
the reasons of the appearance of himodal molecular weight distribution were elucidated and the possible mechanisms of polymerization were discussed.
