Abstract
In an improved start-up procedure for the continuous 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 catalyst composition formed from a palladium compound, the anion of a strong non-hydrohalogenic acid and a bidentate ligand of phosphorus, the start-up period is shortened when the reaction mixture at the start of continuous operation contains previously prepared linear alternating polymer.
