ABSTRACT:
The present invention relates to the production of 1,4-cis-polybutadiene and of copolymers of butadiene with other conjugated diolefins, by means of the catalytic polymerization or copolymerization of monomer butadiene, by an either continuous or batch process, operating in the presence or in the absence of diluents, and carrying out a portionwise addition, during the polymerization, of a portion of the organometallic compound of aluminum (or of the related hydride derivative), constituiting also one of catalytic components.
