ABSTRACT:
Methods of producing polyolefin polymers by polymerizing an .alpha.-olefin in the presence of a catalyst including a pro-catalyst having a magnesium halide, an aluminum halide, a tetravalent titanium halide, an electron donor, and a silane having the formula R.sub.1 R.sub.2 Si(OR.sub.3) (OR.sub.4), wherein R.sub.1 and R.sub.2 are each an H, C.sub.1-6 alkyl, aryl, C.sub.5-12 cycloalkyl, each of which may be unsubstituted, mono- or di-substituted, and R.sub.3 and R.sub.4 are H, C.sub.1-6 alkyl, or a mono- or di-substituted C.sub.1-6 alkyl, and a co-catalyst comprising an organometallic compound, or reaction products of the pro-catalyst and the co-catalyst, wherein the electron donor is present in an amount sufficient to reduce the stickiness of the resultant polyolefin polymers. Moreover, the polymers produced thereby, and methods of preparing resultant products from the polymers are part of the present invention.
