Abstract
Abstract There is disclosed a process for the polymerization of butadiene and butadiene in mixture with other diolefins to form polymers containing a high proportion of the butadiene units in the cis1,4 configuration which comprises contacting said monomer under solution polymerization conditions at temperatures ranging from about -10*C to about 100*C with a catalyst comprising 1. AN ORGANOALUMINUM COMPOUND 2. AN ORGANONICKEL COMPOUND 3. HYDROGEN FLUORIDE.
