Title (EN) CROSSLINKED COMPOSITION COMPRISING ETHYLENE VINYL ACETATE COPOLYMER AND NITRILE RUBBER
(FR) COMPOSITION RÉTICULÉE COMPRENANT UN COPOLYMÈRE ÉTHYLÈNE-ACÉTATE DE VINYLE ET UN CAOUTCHOUC NITRILE
Abstract:
(EN) The present invention relates to a crosslinked composition, in particular for use as a sheath layer of cable, method for preparing it, and a cable comprising it. The crosslinked composition according to the present invention is obtained from polymer blend comprising ethylene vinyl acetate copolymer (EVA), nitrile rubber (NBR) and crosslinking agent, said polymer blend further comprising a reactive polymer containing at least one nucleophilic or electrophilic functional group; and a reactive compound selected from amphiphilic compound containing at least one nucleophilic or electrophilic functional group that can chemically react with nucleophilic or electrophilic functional group of said reactive polymer.
(FR) La présente invention concerne une composition réticulée, en particulier destinée à être utilisée en tant que couche de gaine de câble, son procédé de préparation, et un câble la comprenant. La composition réticulée selon la présente invention est obtenue à partir d'un mélange polymère comprenant un copolymère éthylène-acétate de vinyle (EVA), du caoutchouc nitrile (NBR) et un agent de réticulation, ledit mélange polymère comprenant en outre un polymère réactif contenant au moins un groupe fonctionnel nucléophile ou électrophile ; et un composé réactif sélectionné parmi un composé amphiphile contenant au moins un groupe fonctionnel nucléophile ou électrophile qui peut réagir chimiquement avec un groupe fonctionnel nucléophile ou électrophile dudit polymère réactif.
