ABSTRACT:
The present invention relates to catalysts, to a method for preparing such catalysts, to a method of using such catalysts and to polymeric products produced with such catalysts. The catalysts are particularly useful in the polymerization of - olefins, diolefins and acetylenically unsaturated monomers. The improved catalysts are prepared by combining at least one first compound which is a bis(cyclopentadienyl) derivative of a metal of Group IV-B of the Periodic Table of the Elements capable of forming a cation formally having a coordination number of 3 and a valence of +4 and at least one second compound comprising a cation capable of donating a proton and a compatible noncoordinating anion comprising a plurality of boron atoms, which anion is both bulky and labile, and capable of stabilizing the Group IV-B metal cation without interfering with said Group IV-B metal cation's or its decomposition product's ability to polymerize .alpha.-olefin, diolefins and/or acetylically unsaturated monomers.
