The invention provides a composition comprising the following: at least one olefin multi-block interpolymer, at least one thermoplastic polyurethane, and at least one polydiene-based and/or polydiol-based polyurethane. These compositions are well-suited for promoting the adhesion between polar (for example, polyester, polycarbonate and polylactic acid) and non-polar materials and for the manufacture of, among other things, films, fibers, sheets and tie layers, tubes, adhesives, dispersions, protective apparel, footwear, coatings, laminates and foams.
La présente invention concerne une composition qui comprend: au moins un interpolymère multiséquencé d'oléfine, au moins un polyuréthane thermoplastique, et au moins un polyuréthane à base de polydiène et/ou de polydiol. Ces compositions sont tout à fait appropriées pour favoriser l'adhésion entre des matériaux polaires (par exemple, le polyester, le polycarbonate et l'acide polylactique) et les matériaux non polaires et conviennent pour fabriquer, entre autres, des films, des fibres, des feuilles et des couches d'accrochage, des tubes, des adhésifs, des dispersions, des vêtements protecteurs, des chaussures, des revêtements, des lamellés et des mousses.
