Abstract
The invention is directed towards a metal complex having the formula LMX.sub.1 X.sub.2. L is a bidentate nitrogen-containing ligand with more than two nitrogen atoms. M is copper, silver, or gold. X.sub.1 and X.sub.2 are independently selected from the group consisting of halogens, C.sub.1 through C.sub.12 straight chain, branched, or cycloalkyl or aryl, C.sub.1 through C.sub.12 straight chain, branched, or cycloalkoxy, hydride, triflate, trifluoroacetate, trisperfluorotetraphenylborate, and tetrafluoroborate. Such metal complexes have a tetrahedral or pseudo-tetrahedral structure. The invention relates to a catalyst composition of the reaction product of the metal complex and an activating cocatalyst. The invention is also directed towards a method for forming polymers and copolymers using such catalyst compositions, especially copolymers having segments formed from olefinic monomers and monomers having at least one hydrocarbyl polar functional group.
