Abstract

Process for polymerizing a monomer in the presence of an organolithium initiator, the monomer being chosen from conjugated dienes containing 4 to 12 carbon atoms per molecule and monovinyl aromatic hydrocarbons having 8 to 20 carbon atoms per molecule, in the presence of an initiator of organolithium, adding a non-polymerizable coupling agent which reacts with the resulting lithium polymer to couple the corresponding polymer chains, a process characterized in that the coupling agent is added continuously or intermittently during the polymerization.
