Title
(EN) FUNCTIONALIZED RUBBERS
(FR) CAOUTCHOUCS FONCTIONNALISÉS
Abstract
(EN)
The present invention relates to a process for the functionalization of a rubber polymer comprising reacting the rubber polymer with at least one source of nitrene or carbene, in the presence of a catalyst of formula TpxAg, wherein Tpx represents a hydrotris(pyrazolyl)borate ligand. This process leads to selective rubber functionalization without secondary reactions such as chain scission or cross linking and produces functionalized rubbers with improved compatibilization properties. The invention also refers to the polymer produced therefrom and to uses of said polymer.
(FR)
La présente invention concerne un procédé de fonctionnalisation d'un polymère de caoutchouc comprenant la réaction du polymère de caoutchouc avec au moins une source de nitrène ou de carbène, en présence d'un catalyseur de formule TpxAg, dans laquelle Tpx représente un ligand d'hydrotris(pyrazolyl)borate. Ce procédé conduit à une fonctionnalisation sélective du caoutchouc sans réactions secondaires telles que la scission de chaîne ou la réticulation et produit des caoutchoucs fonctionnalisés ayant des propriétés de compatibilisation améliorées. L'invention concerne également le polymère produit par ce procédé et des utilisations dudit polymère.
