A propylene polymer made using a magnesium halide-supported, titanium- containing solid catalyst component having a broad processing window is produced by incorporating into the polymerization catalyst system a selected alkyl methyldimethoxysilane, preferably isobutylmethyldimethoxysilane. Useful articles made from such resin include OPP film.
L'invention concerne un polymère de propylène produit au moyen d'un catalyseur solide contenant du titane et à support halogénure de magnésiuum, présentant une large plage de températures de mise en oeuvre. C e polymère est produit par incorporation, dans le système catalyseur de polymérisation, d'un alkylméthyldiméthoxysilane sélectionné, de préférence un isobutylméthyldiméthoxysilane. Les films de polypropylène biorienté constituent des articles utiles réalisés à partir d'une telle résine.
