ABSTRACT:
A process is disclosed for the particle form polymerization of olefins. The process employs a titanium-containing having hydrocarbon soluble titanium components. The resulting catalyst is pretreated with an organometallic reducing agent prior to the introduction of the catalyst into the polymerization zone to give a catalyst which can be used satisfactorily in a loop reactor with lower levels of cocatalyst.
