    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a transition metal catalyst with carrier easily practicable on an industrial scale without causing film formation on the inner wall of a reaction vessel so as to uniformly bearing the catalyst on a carrier material. SOLUTION: This method for producing a transition metal catalyst with carrier comprises gradually adding a solution of a transition metal complex based on group VIIIB, IB or IIB element (optionally its mixture with a cocatalyst) to a particulate organic or inorganic carrier material in such a manner that the volume of the solution to be used is double or less the porosity of the carrier material to effect entirely renewing the surface of the carrier material.

    Abstract: A supported catalyst for the production of carbon monoxide copolymers is obtained by suspending the support in non-polar aprotic solvent, adding a solution of a Group VIIIB, IB or IIB metal complex with bi- or tri-dentate ligand(s) in a polar aprotic solvent, possibly adding non- polar solvent and working up by filtration. A process for the production of linear alternating copolymers of carbon monoxide (CO) and olefinically unsaturated compounds uses an activator compound and a supported heterogeneous catalyst system, which is obtained by: (a) suspension of the support material in a non-polar aprotic liquid (NPAL), (b) controlled addition of a Group VIIIB, IB or IIB metal chelate complex with bi- or tri- dentate ligand(s) as a solution in a polar aprotic liquid, (c) filtration, optionally followed by washing with NPAL and (d) optionally removing liquid residues with inert gas. Alternatively, the mixture obtained from stage (b) may be mixed with NPAL before performing stages (c) and (d) as above. An Independent claim is also included for carbon monoxide copolymers obtained by this process.

    Abstract: The invention relates to the production of homopolymers, co-copolymers or block copolymers from cycloolefinic monomer units characterized in that polymerization occurs in the presence of a catalyst of general formula (I), and optionally in the presence of an additive, wherein the substituents and indices have the following meaning: M is a metal from group VIII B of the periodic table of elements; E1, E2 are independently from each other an element from group V A of the periodic table of elements; Z is a bridging structural unit; Ar stands for annelated aryl units independent of each other; L1, L2 stands for formally uncharged Lewis base ligands; X means monovalent or bivalent anions; k means 1 or 2; l, m, n represent 1 or 2, whereby m x n = 1.
