Abstract:
A catalyst system represented by the formulae: ##STR16##wherein R1, R2, and R3 are each independently hydrogen, alkyl, aryl, aralkyl groups, each G is independently hydrogen or a hydrocarbyl group, and g is an integer greater than or equal to 1 representing a number of monomer units --(CH.sub.2 --CG.sub.2)-- incorporated into a polymer chain; andNCA.sup.- is a non-coordinating anion represented by the following general formula:[(M').sup.m+ Q.sub.1. . . Q.sub.n ].sup.d-wherein:M' is a metal or metalloid;Q.sub.1 to Q.sub.n are, independently, bridged or unbridged hydride radicals, dialkylamido radicals, alkoxide and aryloxide radicals, hydrocarbyl and substituted-hydrocarbyl radicals, halocarbyl and substituted-halocarbyl radicals and hydrocarbyl and halocarbyl-substituted organometalloid radicals and any one, but not more than one of Q.sub.1 to Q.sub.n may be a halide radical;m is an integer representing the formal valence charge of M;n is the total number of ligands Q, andd is an integer greater than or equal to 1.
