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.

Disclosed is a method of polymerizing olefin using a compatible combination of a multi-site catalyst and a single-site catalyst. The catalysts may be a Ziegler-Natta catalyst and a metallocene catalyst. The resulting polymer, which may be a homopolymer or a random copolymer, may exhibit a molecular weight distribution which is intermediate than that resulting for polymers prepared using either catalyst alone.

It has been discovered that using n-butylmethyldimethoxysilane (BMDS) as an external electron donor for 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. Consequently, the curve of storage modulus (G') v. temperature is shifted such that the film achieves the same storage modulus at a lower temperature enabling faster throughput of polypropylene film through a high-speed tenter.
