Hyperbranched 1, 4-Cis+1, 2-Polybutadiene Synthesis Using Novel Catalytic Dithiosystems .................................................... and Nazil Fazil oglu Janibayov

Earlier in the Institute of Petrochemical Processes of Azerbaijan National Academy of Sciences (IPCP of ANAS) we have developed the new bifunctional nickel-and cobalt-containing catalytic dithiosystems, which have shown high catalytic activity and stereo selectivity in butadiene polymerization process. Particularly, by using the cobalt-dithiocarbamate catalytic system (diethylditiocarbamate cobalt + alkylaluminummonochloride) it was possible to obtain linear high molecular 1,4-cis+1,2-polybutadiene of high solution viscosity [1].
