PECULIARITIES OF COBALT CATALYTIC-SYSTEMS FOR CIS-POLYMERIZATION OF BUTADIENE - THE NATURE OF ACTIVE-CENTERS

The published data on some peculiarities of cobalt catalysts for cis-p olymerization of butadiene are analyzed. According to the data of the authors, consumption of alkylaluminum chloride can be markedly decreas ed with efficiency of the cobalt system remaining high. On the basis o f data on the use of organocobalt compounds in butadiene polymerizatio n, the nature of cis-stereogulating active centers is discussed.
