Patent

CA 2208980

The present invention relates to a mixture comprising (i) a matrix (A) consisting of polyolefin (A1) and/or a functionalized polyolefin (A2); and (ii) a dispersed phase comprised of an alloy B with polyamide matrix, comprising for example a polyamide (B1), a functionalized polyolefin (B2) and optionally a polyolefin (B3). The invention further relates to a process for producing a mixture according to the invention, particularly a process comprising the step of mixing constituents of matrix (A) and a crushate of a multilayer film comprising at least a layer of alloy B.

La présente invention a pour objet un mélange comprenant (i) une matrice A constituée d'une polyoléfine (A1) et/ou une polyoléfine fonctionnalisée (A2); et (ii) une phase dispersée constituée d'un alliage B à matrice de polyamide, comprenant par exemple un polyamide (B1), une polyoléfine fonctionnalisée (B2) et éventuellement une polyoléfine (B3). L'invention a encore pour objet une procédé de fabrication d'un mélange selon l'invention, en particulier un procédé comprenant l'étape de mélange des constituants de la matrice A et d'un broyat d'un film multicouches comprenant au moins une couche en alliage B.
