(FR) POLYMÈRE GREFFÉ PORTANT DES GROUPES PENDANTS FONCTIONNELS CARBONATES CYCLIQUES
Abstract
(EN)
A first subject of the present invention relates to a modified polymer obtained by grafting at least one compound of formula (I) onto at least one unsaturation of the chain of an initial polymer (formula I) in which - Q is a dipole comprising at least one nitrogen atom; - A is an arenediyl ring, optionally substituted with one or more hydrocarbon-based chains, which may be identical or different, independent of one another, optionally substituted or interrupted with one or more heteroatoms; - E is a hydrocarbon-based divalent linking group which may optionally contain one or more heteroatoms; - R1, R2 and R3 are, independently of one another, a hydrogen atom or a hydrocarbon-based chain optionally substituted or interrupted with one or more heteroatoms; and - n is an integer having a value greater than or equal to 1. The invention also relates to the process for producing such a modified polymer and to compositions comprising a modified polymer.
(FR)
Un premier objet de la présente invention concerne un polymère modifié obtenu par greffage d'au moins un composé de formule (I) sur au moins une insaturation de la chaîne d'un polymère initial (formula I) dans laquelle - Q représente un dipôle comprenant au moins un atome d'azote; - A représente un cycle arènediyle, éventuellement substitué par une ou plusieurs chaînes hydrocarbonées, identiques ou différentes, indépendantes les unes des autres, éventuellement substituées ou interrompues par un ou plusieurs hétéroatomes; - E représente un groupe de liaison divalent hydrocarboné pouvant éventuellement contenir un ou plusieurs hétéroatomes; - R1, R2 et R3 représentent, indépendamment les uns des autres, un atome d'hydrogène ou une chaîne hydrocarbonée éventuellement substituée ou interrompue par un ou plusieurs hétéroatomes; et - n est un entier ayant une valeur supérieure ou égale à 1. L'invention concerne également le procédé de préparation d'un tel polymère modifié et des compositions comprenant un polymère modifié.
