Title
(EN) LAMINAR ARTICLES MADE FROM MIXTURES OF A POLYOLEFIN AND ETHYLENE/VINYL ALCOHOL COPOLYMERS
(FR) ARTICLES LAMINAIRES OBTENUS A PARTIR DE MELANGES D'UNE POLYOLEFINE ET DE COPOLYMERES D'ETHYLENE/ALCOOL VINYLIQUE
Abstract
(EN)
A laminar article is provided, comprising a combination of a polyolefin, an ethylene-vinyl alcohol copolymer having a melting point at least about 5°C higher than the polyolefin, and a compatibilizer of a compatible polyolefin backbone grafted with cyclic anhydride moieties, wherein the ethylene-vinyl alcohol copolymer is present within the polyolefin as multiple, thin, substantially parallel, overlapping layers.
(FR)
Un article laminaire comprend une combinaison d'une polyoléfine, d'un copolymère d'éthylène/alcool vinylique ayant un point de fusion d'au moins 5°C environ supérieur à celui de la polyoléfine, et un agent de compatibilité d'une ossature de polyoléfine compatible sur laquelle a été greffé des fractions anhydrides cycliques, le copolymère d'éthylène/alcool vinylique étant présent dans la polyoléfine sous la forme de multiples couches minces sensiblement parallèles et se chevauchant.
