Abstract
Aluminoxanes having C2-C10 alkyl groups can conveniently be used in supported olefin polymerization catalyst compositions prepared by contacting a support comprising a solid compound which is one of pure aluminium oxide, a mixed aluminium oxide, an aluminium salt, a magnesium halide, or a C1-C8 alkoxy magnesium halide, in any order with at leasta) an organometallic compound,b) a metallocene, andc) an aluminoxane,and recovering said supported olefin polymerization catalyst composition.
