ABSTRACT:
It has been discovered that using n-butylmethyldimethoxysilane (BMDS) as an external electron donor for succinate-containing Ziegler-Natta catalysts can provide a catalyst system that may prepare polypropylene films with improved properties. The catalyst systems of the invention provide for controlled chain defects/defect distribution and thus a regulated microtacticity along with broadened molecular weight distribution.
