<p>Catalysts are produced by: (a) dissolving Main Group 1 or 2 metal derivatives of 2,6-difunctionalised phenylazo compounds in a non-polar solvent; (b) dissolving Sub-Group 4-12 compounds with up to 4 neutral and/or anionic ligands in a polar solvent; and (c) mixing the solutions. A method (M1) for the production of a catalyst involves: (a) dissolving compounds of formula (I) in a non-polar solvent; (b) dissolving metal compounds of formula M(L 1>)W(L2)Y(L3)Z (II) in a polar solvent; and (c) mixing the two solutions.

Independent claims are also included for: (1) catalysts obtained by this method (M1) (2) a method (M2) for the production of olefin (co)polymers by reacting these catalysts in presence of optionally functionalized 1-olefins and/or cyclo-olefins (3) products obtained by reacting these catalysts with co-catalysts (4) olefin (co)polymers obtained by M2 (5) molded parts obtained by processing these (co)polymers.</p> |
