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 1):
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 of R 6  and R 7  is independently H or a C 1  to C 18  hydrocarbyl group; or, R 6  and R 7  together form one or more saturated or unsaturated mono- or poly-cyclic structures; \n each R 8  is independently absent, H, or a C 1  to C 18  hydrocarbyl group; \n m is 0 or 1; \n wherein each of R 5 , R 6 , R 7 , and R 8 , 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 selected from the group consisting of:\n i) a triester compound having a formula of \n ii) a diester compound having a formula of and iii) an oxo-substituted diester compound having a formula of wherein: X is CH 2  or O, each R is independently a C 1 -C 10  hydrocarbyl group, each R\u2032 is independently H or R, each n is independently an integer from 1 to 4, and n\u2032 is an integer from 0 to 4.
