Production of carbon monoxide-olefin copolymers, used for production of fibers, film and molded products

摘要

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.
