Heterocyclic organic compounds as electron donors for polyolefin catalysts |
| 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.” |
