Abstract
Organosilicon compounds having a structure represented by the general formula and a method for using same are provided as electron donors in the Ziegler-Natta type catalyst system for the homo-polymerization or co-polymerization of alpha olefins. The organosilicon compounds may be used in the preparation of the solid catalyst component, thus serving as 'internal electron donors', or employed during or prior to polymerization as 'external electron donors,' and therefore they can be used to prepare phthalate-free polyolefins.
