PROPYLENPOLYMERHARZ HERGESTELLT MIT EINEM HOCHAKTIVEN KATALYSATOR, MIT EINEM GROSSEN TERMISCHEN VERARBEITUNGSBREITE, UND DARAUS HERGESTELLTE FORMTEILE

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.
