More Information
Summary:The present invention is related to a method of manufacture of high-activity silica-impregnated polymerization catalysts with which ethylene singly or alpha-olefin copolymers may be manufactured. More concretely, the present invention is related to a method of manufacture of new high-activity Ziegler-Natta catalysts through the successive impregnation of Ziegler-Natta catalytic components in a specific titanium group into spherical silica supports, simultaneous production of the primary activation sites and the secondary activation sites, and activation of catalysts, as well as new polyolefin polymerization catalysts manufactured according to the above method.
