A novel metallocene catalyst for the polymerization of olefin (co)polymers is of the general formula:R-SO2-L-M-(X)mTnwherein, M is a metal selected from Groups 3-10; T is a polymerization-stable anionic ancillary ligand; m+n is the valency of M minus 1; R is a C1-C20 alkyl group, a C6-C20 aryl ring or a C6-C20 alkaryl or aralkyl group, optionally substituted with a halogen or an alkoxy group up to 10 carbon atoms; X is a halogen, alkoxy from C1 to C20, siloxy from C1 to C20, N(R)2, a hydrocarbyl group containing up to about 12 carbon atoms, hydrogen or another univalent anionic ligand, or mixtures thereof; L is T as defined above with the proviso that one of the sites available for substitution is the attachment site of the sulfonyl group; and wherein L and T may be bridged. |
