Title (EN) PRODUCTION OF CIS-1,4-POLYDIENES WITH MULTIPLE SILANE FUNCTIONAL GROUPS PREPARED BY IN-SITU HYDROSILYLATION OF POLYMER CEMENT
(FR) PRODUCTION DE CIS-1,4-POLYDIÈNES AVEC DE MULTIPLES GROUPES FONCTIONNELS SILANE PRÉPARÉS PAR HYDROSILYLATION IN SITU DE POLYMÈRE-CIMENT
Abstract:
(EN) A method of preparing a silane-functionalized polymer, the method comprising: preparing a polymerization system including a cis-l,4-polydiene by introducing a lanthanide-based catalyst and a conjugated diene monomer; and adding a hydrosilane compound to the polymerization system including a cis-l,4-polydiene.
(FR) L'invention concerne un procédé de préparation d'un polymère à fonction silane, le procédé consistant à : préparer un système de polymérisation comprenant un cis-1,4-polydiène par introduction d'un catalyseur à base de lanthanide et d'un monomère diène conjugué; et ajouter un composé hydrosilane au système de polymérisation comprenant un cis-1,4-polydiène.
