ABSTRACT:
Polyketones can be formed in enhanced yield by conducting the polymerization of the carbon monoxide and olefin monomers used to form the polyketone in a gas phase polymerization process in the presence of an effective amount of a liquid, non-polymerizable diluent which is effective in increasing the amount of polyketone formed over that which would be formed in the substantial absence of the diluent. Preferably, the catalyst is supported on a high surface area support (e.g., a carbon monoxide-ethylene high surface area support). Hydrogen gas can be used to reduce the molecular weight and increase the bulk density and thermal stability of the polyketone product.
