Patent
CA 2415856
The invention provides a novel metal complex which, when used with an activating cocatalyst, provides a novel catalyst composition. The invention also provides a polymerization method which utilizes the catalyst composition to produce polymers and copolymers containing polar monomer groups. More specifically, the invention comprises a composition compromising the formula LMXZn wherein X is selected from the group consisting of halides, hydride, triflate, acetates, borates, C1 through C12 alkyl, C1 through C12 alkoxy, C3 through C12 cycloalkyl, C3 through C12 cycloalkoxy, aryl, thiolates, carbon monoxide, cyanate, olefins, and any other moiety into which a monomer can insert. M is selected from the group consisting of Cu, Ag, and Au. L is a nitrogen-containing bidentate ligand having more than two nitrogen atoms. Z is a neutral coordinating ligand and n equals 0, 1, or 2.
Cette invention concerne un nouveau complexe de métaux qui, lorsqu'il est utilisé avec un cocatalyseur activant, donne une nouvelle composition catalysante. Elle concerne également un procédé de polymérisation qui met en oeuvre la composition catalysante pour produire des polymères et des copolymères contenant des groupes monomères polaires. Plus particulièrement, l'invention concerne une composition de la formule LMXZ¿n? dans laquelle X est sélectionné dans le groupe constitué par halogénures, hydrure, triflate, acétates, borates, alkyle C¿1?-C¿12?, alcoxy C¿1?-C¿12?, cycloalkyle C¿3?-C¿12?, cycloalcoxy C¿3?-C¿12?, aryle, thiolates, oxyde de carbone, cyanate, oléfines, et tout autre fragment dans lequel un monomère peut s'insérer. M est sélectionné dans le groupe constitué par Cu, Ag et Au. L est un ligand bidenté contenant de l'azote et présentant plus de deux atomes d'azote. Z est un ligand de coordination neutre, et n est 0, 1 ou 2.
