Abstract
Supported olefin, e.g., alpha-olefin, polymerization catalyst compositions, such as Ziegler-Natta catalysts, are modified by using porous, polymer particles having an average pore diameter of at least about 10 .ANG. as the catalyst support. The resulting catalyst composition is more active than refractory oxide-supported catalysts and it is not susceptible to deactivation by catalyst poisons, such as oxygen or water. Additionally, the polymer particles need not be calcined prior to the catalyst synthesis.
