简介 The invention relates to a continuous method for producing a diene elastomer, comprising a polymerisation reaction of a catalyst system with at least one conjugated diene monomer to be polymerised in solution in a solvent, said catalyst system containing at least one rare earth organic salt and an alkylation agent, in at least two full polymerisation reactors in series, characterised in that a portion of the conjugated diene monomer to be polymerised is introduced into a polymerisation reactor subsequent to the first polymerisation reactor.
