Abstract[English]
A method for the synthesis of an elastomer comprising the steps of polymerizing conjugated diene monomer in presence of at least one rare earth transition metal catalyst system to generate a polydiene cement; terminating the polydiene cement with a protic organic compound; connecting polymer chains by reacting (1) a compound containing sulfur and a halogen with (2) an acrylate; and adding a product of the reaction to the cement to generate a poly diene rubber.[French]
L'invention concerne un procédé de synthèse d'un élastomère comprenant les étapes consistant à polymériser un monomère diène conjugué en présence d'au moins un système catalytique de métal de transition du groupe des terres rares pour créer un ciment polydiène; terminer le ciment polydiène avec un composé organique protique; relier les chaînes polymères par mise à réagir (1) d'un composé contenant du soufre et d'un halogène avec (2) un acrylate; et à ajouter un produit de la réaction au ciment pour générer un caoutchouc polydiène.
