The invention provides a process for the polymerisation of conjugated diene monomers which comprises anionically polymerising the monomers in the presence of an anionic polymerisation initiator and a microstructure control agent for controlling the vinyl content of the polymer so obtained, whereby the control agent is added to the polymerisation mixture in two or more doses, or continuously.
Méthode pour la polymérisation de monomères diéniques conjugués, consistant à polymériser les monomères par voie anionique, en présence d'un initiateur anionique de polymérisation et d'un agent de régulation microstructural pour réguler la teneur en vinyle du polymère ainsi obtenu; l'agent de régulation est ajouté au mélange de polymérisation en deux ou plusieurs doses, ou en continu.
