A continuous method for producing a diene elastomer is provided. The method comprises a polymerization reaction of a catalytic system with at least one conjugated diene monomer to be polymerized in solution in a solvent. The catalytic system is based on at least a rare earth organic salt and an alkylating agent, in at least two full polymerization reactors in series. A portion of the conjugated diene monomer to be polymerized is introduced into a polymerization reactor subsequent to the first polymerization reactor.

Continuous method for producing a diene elastomer

An ethylene/1,3-butadiene copolymer containing ethylene units, butadiene units and UD units of cyclic, 1,2-cyclohexanediyl structure, and bearing, at one of its chain ends, an alkoxysilyl or silanol function, functional group Fis provided. The UD units of cyclic structure are of the following formula: 

Functional ethylene and 1,3-butadiene copolymer

A copolymer of a 1,3-diene and of an olefin selected from the group consisting of &#x3b1;-monoolefins, ethylene and mixtures thereof is provided. The copolymer bears, at one of its chain ends, an alkoxysilyl or silanol function, functional group F, and the copolymer is different from a copolymer of a 1,3-diene and a vinylaromatic monomer.
