Title (EN) PROCESS FOR PREPARING A STATISTICAL COPOLYMER BASED ON ACYCLIC DIENE MONOMERS AND CYCLIC DIENE MONOMERS, COPOLYMERS AND COMPOSITIONS CONTAINING SAME
(FR) PROCEDE DE PREPARATION D'UN COPOLYMERE STATISTIQUE A BASE DE MONOMERE DIENIQUE ACYCLIQUE ET DE MONOMERE DIENIQUE CYCLIQUE, COPOLYMERES ET COMPOSITIONS LES COMPRENANT
Abstract:
(EN) The present invention relates to a process for preparing a statistical copolymer based on acyclic diene monomers and cyclic diene monomers, characterised in that it comprises a copolymerisation step in the presence of a polar agent and an anionic initiator in a polymerisation solvent, for polymerising at least one acyclic diene monomer and at least one cyclic diene monomer, including an endocyclic, C=C double bond conjugated with an exocyclic, C=C double bond, at a polymerisation temperature of less than 80°C, with a [polar agent/anionic initiator function] molar ratio of more than 0.1. The present invention also relates to these copolymers and to the compositions containing same.
(FR) La présente invention concerne un procédé de préparation d'un copolymère statistique à base de monomères diéniques acycliques et de monomères diéniques cycliques, caractérisé en ce qu'il comprend une étape de copolymérisation, en présence d'un agent polaire et d'un amorceur anionique dans un solvant de polymérisation, d'au moins un monomère diénique acycliqueet d'au moins un monomère diénique cyclique dont une double liaison C=C est endocyclique et conjuguée à une double liaison C=C exocyclique, à une température de polymérisation inférieure à 80°C, le rapport molaire [agent polaire/fonction de l'amorceur anionique] étant supérieur à 0,1. La présente invention concerne également de tels copolymères et les compositions les contenant.
