Abstract:
This invention relates to a non-phthalate catalyst system for olefin polymerization. The non-phthalate catalyst system comprises (a) a solid Ziegler-Natta catalyst composition comprising a transition metal, a Group 2 metal, and one or more halogens; and one or more internal electron donor compounds; and (b) one or more external electron donor compounds.

Claim (Index 7):
The non-phthalate catalyst system of  claim 1 , wherein the internal electron donor compound is a diester compound having a formula of: wherein:\n each m\u2032 is 0-3; \n each R 17  is independently H, halogen, or a C 1  to C 18  hydrocarbyl group which can optionally form one or more saturated or unsaturated cyclic structures with the phenyl group it attaches to, and can contain one or more heteroatoms that replace one or more carbon atoms in the hydrocarbyl group, wherein the one or more heteroatoms are selected from the group consisting of halogens, P, N, O, S, and Si; and \n each R 5  is independently a C 1 -C 10  alkyl, C 2 -C 10  alkenyl, C 5 -C 6  cycloalkyl, C 5 -C 6  cycloalkenyl, aryl, or heteroaryl; each of these groups can be further substituted by halogen, C 1 -C 10  alkyl, or C 1 -C 10  alkoxy.
