SUPPORTED OLEFIN POLYMERIZATION CATALYST, ITS PREPARATION AND USE

摘要

Until now, olefin polymerization catalysts based on a metallocene, an alumox ane and a support have been highly uneven in quality. A new process had now been developed for the preparation of a supported olefin polymerization catalyst, wherein (a) a metallocene/acti vator reaction product, a solvent capable of dissolving it, and a porous support a re brought into mutual contact, and (b) the solvent is r emoved, and wherein step (a) is carried out so that the porous support is impregnate d with an amount at maximum its pore volume of the metallocene/activator reaction product and solvent.
