A process for preparing a random copolymer based on at least one acyclic diene monomers and on at least one cyclic diene monomer is provided. The process comprises a step of copolymerization, in the presence of a polar agent and an anionic initiator in a polymerization solvent, of at least one acyclic diene monomer and of at least one cyclic diene monomer of which one C═C double bond is endocyclic and conjugated to an exocyclic C═C double bond, at a polymerization temperature below 80° C. A molar ratio of the polar agent/function(s) of the anionic initiator capable of initiating anionic polymerization being greater than 0.1.Copolymers based on at least one acyclic diene monomer and on at least one cyclic diene monomer and the compositions containing them are also provided.
