    Abstract: Solution polymerization of conjugated dienes in a vinyl aromatic compound is carried out using a lanthanide metal alkenyl complex and organoaluminum or boron co-catalyst. A process for the solution of conjugated dienes in a vinyl aromatic compound in the presence of a catalyst is claimed. The catalyst is prepared by reaction of an alkenyl complex of a lanthanide metal with a co-catalyst comprising: (A) an organoaluminum compound of formula (1)-(6); and (B) a boron compound of formula (7).
