ABSTRACT:
Olefin polymerization catalyst can be obtained by mixing a transition metal compound (e.g. TiCl.sub.3) and an adjuvant selected from specific hindered phenols, esters of thiodialkanoic acids, esters of phosphorous acid and esters of phosphoric acid; the adjuvants are compatible with FDA regulations for food.
