Abstract
Process for the preparation of butadiene polymers, characterized in that butadiene is selectively polymerized from a mixture comprising butadiene and butene or butenes with a catalyst comprising a mixture or a reaction product of a heavy metal halide selected from the group consisting of cobalt, nickel halide and mixtures thereof and an activating agent selected from the group consisting of a reducing-brightening agent, a friedel-kraft compound and mixtures thereof, the polymerization being carried out in a liquid phase.
