ABSTRACT:
A catalyst component useful in the polymerization of olefins is disclosed. The catalyst component comprises the product obtained by steps of (a) contacting silica with at least one hydrocarbon soluble magnesium-containing compound; (b) contacting the product of step (a) with component (1), a heterocyclic fused ring compound substituted with at least one oxygen atom, and component (2), a modifying compound selected from the group consisting of silicon halides, boron halides, aluminum halides, alkyl silicon halides and mixtures thereof, with the proviso that components (1) and (2) be present such that the molar ratio of component (2) to component (1) is at least about 4:1; and (c) contacting the product of step (b) with a titanium-containing compound having the structural formula TiX.sub.m (OR).sub.n, where X is halogen; R is hydrocarbyl; m is an integer of 1 to 4; and n is 0 or an integer of 1 to 3 with the proviso that the sum of m and n is 4. A catalyst system, used in the polymerization of alpha-olefins, which comprises the catalyst component of this disclosure, an aluminum-containing compound and a silane compound is also taught. Finally, a process for the polymerization of alpha-olefins, utilizing the catalyst system of the present disclosure, is described.
