Abrégé
(EN)
A secondarily modified block copolymer which is obtained by reacting: a primarily modified block copolymer which comprises a base block copolymer comprising at least one polymer block consisting mainly of vinylaromatic hydrocarbon monomer units and at least one polymer block consisting mainly of conjugated diene monomer units and functional−group−containing primary modifier groups bonded to the base block copolymer; with a secondary modifier having a specific functional group reactive with the functional groups of the primary modifier groups contained in the primarily modified block copolymer. Also provided is a polymer composition which comprises the secondarily modified block copolymer in combination with a thermoplastic resin and/or a rubbery polymer.

La présente invention concerne un copolymère séquencé à modification secondaire que l'on obtient en mettant à réagir : un copolymère séquencé à modification primaire qui comprend un copolymère séquencé de base renfermant au moins une séquence polymérique séquencée composée principalement d'unités monomères hydrocarbonées de vinyle aromatique et au moins une séquence polymérique composée principalement d'unités monomères de diène conjugué et de groupes modificateurs primaires contenant des groupes fonctionnels liés au copolymère séquencé de base ; avec un modificateur secondaire renfermant un groupe fonctionnel spécifique réagissant avec les groupes fonctionnels des groupes modificateurs primaires contenus dans le copolymère séquencé à modification primaire. L'invention se rapporte également à une composition de polymère qui comprend le copolymère séquencé à modification secondaire combiné a une résine thermoplastique et/ou un polymère caoutchouc.
