Abstract

A process for the discontinuous copolymerization of at least one conjugated diene, containing a maximum of 5 carbon atoms, and at least one vinylaromatic compound, in the presence of a liquid diluent and with the help of a lithium-based initiator, characterized in that : (a) A starting mix is first prepared from the diluent and part of the total amount needed from each. of the monomers, using a proportion of monomers that, under the polymerization conditions, leads to the desired copolymer; (b) subsequently copolymerization is initiated by contacting this mixture with the initiator; and (c) during copolymerization the proportion of monomers is kept constant by adding the remaining part of each of the monomers.
