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 20):
A non-phthalate catalyst system for olefin polymerization, comprising:\n (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 having the structure of a diester compound having a formula of wherein:\n each R 5  is independently a C 1  to C 18  hydrocarbyl group which can optionally form one or more saturated or unsaturated mono- or poly-cyclic structures; \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; \n each m\u2032 is independently an integer from 0 to 5; and \n wherein each of R 5  and R 17  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 (b) one or more external electron donor compounds having a formula of wherein: each R is independently a C 1  to C 10  hydrocarbyl group, 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; R\u2032 is H or R, and n is an integer from 1 to 10, wherein the external electron donor compound does not contain an alkoxysilane compound.
