A nonaqueous dispersion polymerization process can offer many distinct advantages over other polymerization techniques including: improved heat transfer, increased production capacity, and energy savings. This invention discloses a process for the nonaqueous dispersion polymerization of butadiene monomer in a reaction mixture containing a liquid nonaqueous dispersion medium, the improvement which comprises carrying out the polymerization of the butadiene monomer in the presence of random copolymers of butadiene and isoprene, to produce very high cis-1,4-polybutadiene.
