ABSTRACT:
Specific catalyst modifiers, namely unsaturated diazobicyclo compounds in association with anionic initiators such as organo-lithium compounds are utilized during the polymerization of conjugated diene monomers and comonomers therewith to unexpectantly yield polymers or copolymers having a broad molecular weight distribution, a significant vinyl microstructure, and good processability.
