Abstract
Polyolefins are prepared wherein at least about ninety-five percent of the product is retained on a 100 mesh screen. The polymerization process involves contacting the alpha-olefin with a Ziegler catalyst system wherein the catalyst has been prepared by mixing the active catalytic particles with a fibrillatable polyolefin and a non-fibrillatable polyolefin followed by ballmilling the mixture for a period of time sufficient to cause a fibrous mat to form, entrapping the catalyst particles in the mat which is, in turn, carried by the non-fibrillatable polyolefin.
