PROPYLENE POLYMER RESIN MADE FROM A HIGH ACTIVITY CATALYST HAVING A BROAD THERMAL PROCESSING WINDOW AND ARTICLES MADE THEREFROM

摘要

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 isobutylmethyl-dimethoxysilane. Useful articles made from such resin include OPP film.
