Abstract

An olefin polymerization catalyst system comprising an organic transition metal compound and a support, wherein an organic transition metal compound is soluble in an inert organic solvent and a support which is insoluble in the inert organic solvent, and the support comprises an organic high molecular weight compound which contains a specific carbonyl-containing group. The catalyst system can polymerize an olefin in a high activity, provides polymer with high stereoregularity, prevents adhesion or fouling of the polymer generated in the course of polymerization or an organic aluminum oxy compound on the inner wall of the reactor, leads to high bulk density of the polymer and very reduced level of fisheye and/or gel generation on the processed item, can maintain high productivity, can manufacture high quality product, and thus provides extremely high contribution in industry.
