Patent

CA 2569010

The invention relates to a polymer blend of a polypropylene and/or a polypropylene copolymer and a further polymer which is non-compatible with the polypropylene copolymer. The polymer is obtained by mixing the melts of both polymers with a high energy input and, after cooling and renewed melting and further processing, for example, injection moulding, displays no separation of the phases. The invention relates to a polymer blend such as may be obtained by said method and a moulded body made from the polymer blend.

L'invention concerne un mélange polymérique contenant un polypropylène et/ou un copolymère de polypropylène et un autre polymère incompatible avec le polypropylène et/ou le copolymère de polypropylène. Le polymère est obtenu par mélange des masses fondues Schmelzen des deux polymères avec un apport élevé d'énergie. Il n'apparaît aucune séparation des phases après un refroidissement et une nouvelle fusion et un retraitement, par exemple, par moulage par injection. L'invention concerne également un mélange polymérique obtenu par le procédé selon l'invention et un corps moulé à partir du mélange polymérique.
