Abstract

Procedure for copolymerizing a diene conjugated with a compound with monoalkohylenic unsaturation, polymerizable anionically, in the presence of a solvent for the monomers, with the aid of an anionic initiator as catalyst, which comprises carrying out the polymerization in the presence of at least one cocatalyst comprising a compound and/or metal or metalloid complex, which is soluble in the reaction medium and has oxidizing properties, and which is neither titanium nor vanadium compound or complex.
