Abstract
An improved process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon in a large scale reactor equipped with a stirring device under polymerization conditions in the presence of a catalyst composition and liquid reaction diluent, which is characterized by the provision of a certain minimum power density by the stirring device to the polymer suspension formed during polymerization. The linear alternating polymer so produced will have an improved bulk density.
