ABSTRACT:
An improved catalyst for the polymerization of olefins comprising at least one metallocene and at least one aluminoxane co-catalyst supported on a substrate comprising a cross-linked polymeric, porous, resin wherein at least one of the monomers in the resin has at least one pendant functional group which is not reactive under the conditions of the formation of the substrate, and therefore survives the copolymerization which forms the substrate. One specific cross-linked resin is a copolymer of styrene, divinyl benzene and acetoxy styrene.
