Abstract:
Heterocyclic organic compounds are used as electron donors in conjunction with solid Ziegler-Natta type catalyst in processes in which polyolefins such as polypropylene are produced. The electron donors may be used in the preparation of solid catalyst system, thus serving as “internal electron donors,” or they may be employed during or prior to polymerization with the co-catalyst as “external electron donors.”

Claim (Index 10):
A catalyst system for the polymerization or co-polymerization of alpha-olefins comprising:\n (1) a solid catalyst component for the polymerization or co-polymerization of alpha-olefin comprising titanium, magnesium, halogen and at least one internal electron donor selected from heterocyclic organic compounds of: wherein L is represented by: or is selected from the group consisting of \u2014OR 9 , \u2014SR 9 , \u2014OCOR 9 , \u2014COOR S , \u2014NH 2 , \u2014NHR 9 , \u2014NR 9 2, and PR 9 2  \n wherein R 9  is selected from the group consisting of a linear or branch C 1 -C 20  alkyl, C 2 -C 20  alkenyl, C 3 -C 20  cycloalkyl, C 6 -C 20  aryl, C 7 -C 20  alkylaryl, and C 7 -C 20  arylalkyl; \n wherein A and At, which may be identical or different, is a carbon atom or a hetcroatom selected from the group consisting of Si, N, B, and P; \n wherein Q and Q1, which may be identical or different, is a heteroatom selected from the group consisting of O, N, S, and P; \n wherein R\u2032, R 4 , R 5 , and R 8 , which may be identical or different, are aliphatic, alicyclic or aromatic groups; \n wherein the subscripts p, q, i, and j are independently selected from 0 or 1; \n wherein the bonds directly connected to Q, A, Qi, and A 1 , are independently a single bond or a double bond; \n wherein R, R 2 , R 3 , R 6 , and R 7 , which may be identical or different, are bridging groups with a backbone chain length being 1-6 atoms for R and 0-6 atoms for R 2 , R 3 , R 6 , and R 7 , wherein the resultant ring structure is a three to eight-membered ring; \n (2) a co-catalyst component.
