Abstract
An improved gas-phase process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon employs a novel supported catalyst wherein the physical properties and dimensions of the catalyst support exhibit a defined mathematical relationship. Specifically, the value obtained when the average particle size of the particulate catalyst support is raised to the power of the relative bulk density of the support should be less than 30.
