ABSTRACT:
In an improved continuous process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon by contacting the carbon monoxide and hydrocarbon under polymerization conditions in the presence of a reaction diluent and a catalytic quantity of a catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid and a bidentate ligand of phosphorus, an improved start-up procedure is employed in which the catalyst composition concentration in the reaction diluent is increased until steady state polymerization is reached.
