COMPONENTS AND CATALYSTS FOR THE POLYMERIZATION OF OLEFINS

摘要

Catalyst components for the polymerization of olefins comprising a titanium or vanadium compound supported on a porous particulate polymeric support which particles have a porosity greater than 0.3 cc/g and a pore distribution such that at least 40% of the pores have radius greater than 150 ANGSTROM . The catalyst components are prepared by impregnating the polymeric support with a solution of the Ti or V compound and evaporating the solvent.
