Title (EN) IMPROVED ADHESION OF POLYOLEFINS TO POLYESTERS
(FR) ADHÉRENCE AMÉLIORÉE DE POLYOLÉFINES À DES POLYESTERS
Abstract:
(EN) The use of a block copolymer of the following structure. Wherein R and R1 may be the same or different and each independently represents an alkyl or aryl group, X may be hydrogen or C1 to C20 alkyl group which may be branched or linear and wherein the aromatic ring substituent joined to polymer B is positioned meta or para to the aromatic ring substituent joined to polymer A and, wherein polymer A is a polymer (or copolymer) of ethylene and polymer B is a polymer of monomers selected from vinyl acetate, C1 - C9 acrylate esters, acrylic acid and mixtures thereof as an additive in polyethylene or polyethylene terephthalate to improve the adhesion between co-extruded layers of the polyethylene and the polyethylene terephthalate and laminated films derived from such use.
(FR) L'invention concerne l'utilisation d'un copolymère séquencé ayant la structure suivante. dans laquelle structure R et R1 peuvent être identiques ou différents et représentent chacun indépendamment un groupe alkyle ou aryle, X peut représenter l'atome d'hydrogène ou un groupe alkyle en C1 à C20 qui peut être ramifié ou linéaire, le substituant sur le noyau aromatique lié au polymère B est en position méta ou para par rapport au substituant sur le noyau aromatique lié au polymère A et le polymère A est un polymère (ou copolymère) d'éthylène et le polymère B est un polymère de monomères choisis parmi l'acétate de vinyle, les esters de type acrylate en C1-C9, l'acide acrylique et les mélanges de ceux-ci, en tant qu'additif dans du polyéthylène ou du poly(téréphtalate d'éthylène) pour améliorer l'adhérence entre des couches coextrudées du polyéthylène et du poly(téréphtalate d'éthylène). L'invention concerne également des films stratifiés dérivés d'une telle utilisation.
