US Classification:

526161, 526164, 526319, 526324, 526320, 5263297, 526327

Abstract:

The invention is directed towards substantially linear copolymers formed using a metal complex having the formula LMX X. L is a bidentate nitrogen-containing ligand with more than 2 nitrogens. M is copper, silver, or gold. X and X are independently selected from the group consisting of halogens, hydride, triflate, acetate, trifluoroacetate, perfluorotetraphenylborate, tetrafluoroborate, C through C alkyl, C through C alkoxy, C through C cycloalkyl, C through C cycloalkoxy, aryl, and any other moiety into which a monomer can insert. Such metal complexes have a tetrahedral or pseudo-tetrahedral structure and may be used with an activating cocatalyst. The invention is derived from 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.
