Abstract
High activity catalyst component for olefin polymerization comprises reaction product of Group IVB-VB metal-containing component with product prepared by reaction of components comprising magnesium alcoholate and halocarboxylic acid, provided that when such components contain less than an effective amount of halogen, reaction product is reacted with halogenating agent. Magnesium alcoholate-halocarboxylic acid reaction product can be obtained in hydrocarbon-soluble or -insoluble form such that catalyst component preparation involves a liquid-liquid or liquid-solid system as desired. Catalysts comprising the above-described component and organometallic promoter are sufficiently active to eliminate need for removal of catalyst residues from polyolefins produced in the presence thereof.
