Abstract: Olefins were polymd. by conveying an inactive high-yield Ti catalyst component to a vapor-phase polymn. reactor with a liq. comprising recycled quench liq., reactivating the Ti catalyst component inside the reactor with a metal alkyl reducing agent, and polymg. the olefin under gas-phase polymn. conditions with the reactivated catalyst to form a polyolefin having a low level of catalyst residue.

Abstract: Vapor phase polymerization of an olefin which comprises conveying inactive high yield titanium catalyst component to a vapor phase polymerization reactor with a liquid comprising recycled quench liquid, reactivating said inactive high yield titanium catalyst component inside the reactor with a metal alkyl reducing agent and polymerizing olefin under gas phase polymerization conditions with reactivated high yield catalyst to form a resinous polymer of an olefin having a low level of catalyst residues.
