CA 2356249

A combination of a low flexural modulus and low crystallinity polyolefin and a functionalized polyolefin were found to result in an olefin composition with excellent adhesion to metals and polar polymers (e.g. polyesters, polyamides, etc) especially fibers therefrom. When these two polyolefins were added to a thermoplastic vulcanizate (e.g. used to partially or fully replace the semicrystalline polyolefin or a thermoplastic vulcanizate), the thermoplastic vulcanizate was found to have the necessary adhesion to form fiber reinforced thermoplastic vulcanizate.

La présente invention concerne une combinaison d'une polyoléfine à faible cristallinité et à bas module de flexion et d'une polyoléfine fonctionnalisée présentant une forte adhésion sur des métaux et des polymères polaires (par exemple des polyesters, polyamides, etc), plus spécialement sur leurs fibres. Lorsque ces deux polyoléfines sont ajoutées à un vulcanisat thermoplastique (par exemple utilisé dans le remplacement partiel ou complet de polyoléfine semi-cristalline d'un vulcanisat thermoplastique), ce vulcanisat présente l'adhésion nécessaire afin de former un vulcanisat thermoplastique renforcé en fibres.
