Abstract
Linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are produced in a continous flow reactor under conditions that result in a bulk density greater than 0.2 g/ml. The polymers are produced by polymerizing carbon monoxide and one or more olefinically unsaturated compounds in a continuous flow reactor in the presence of a palladium catalyst composition, the polymerization occuring in a liquid diluent in which the polymer product is almost or entirely insoluble, and by maintaining the polymerization at steady state wherein the ratio of the quantity of the polymer product formed per hour to the quantity of the polymer product in the reactor is less than 0.2.
