Abstract

A PROCESS OF PRODUCING A CONJUGATED DIENE POLYMER COMPRISING POLYMERIZING A CONJUGATED DIENE MONOMER IN THE PRESENCE OF A CATALYST SYSTEM COMPRISING (A) A COBALT COMPOUND, (B) AN ORGANIC COMPOUND OF A GROUP 13 ELEMENT OF THE PERIODIC TABLE, AND (C) WATER, WHEREIN THE MOLECULAR WEIGHT OF THE CONJUGATED DIENE POLYMER IS CONTROLLED BY ANY ONE OF (I) AND (II), A METHOD COMPRISING ADDING AS A MOLECULAR WEIGHT REGULATOR TO A POLYMERIZATION SOLVENT, (III) AND (IV), A METHOD COMPRISING PREVIOUSLY BRINGING A POLYMERIZATION SOLVENT INTO CONTACT WITH A MOLECULAR WEIGHT REGULATOR, (V), A METHOD COMPRISING USING AN ACYCLIC OLEFIN AS A MOLECULAR WEIGHT REGULATOR AND (VI), A METHOD COMPRISING USING AS A MOLECULAR WEIGHT REGULATOR. A PROCESS OF PRODUCING A POLYBUTADIENE COMPOSITION COMPRISING CIS-1,4 POLYMERIZATION OF 1,3-BUTADIENE BY THE ABOVE-DESCRIBED PROCESS AND THEN SYNDIOTACTIC 1,2 POLYMERIZATION IN THE SAME REACTION SYSTEM IN THE PRESENCE OF A SULFUR COMPOUND.
