Abstract
It is herein disclosed process for the preparation of copolymers of carbon monoxide and one or more ethylenically unsaturated compounds by reacting the monomers under polymerization conditions in the presence of a catalyst system based on a) a source of cations of one or more metals of Group VIII of the Periodic Table, and b) a source of anions, in the further presence of a diluent in which the copolymers are insoluble or virtually insoluble and of a minor amount of one or more non-ionic surfactant.

A process for the preparation of copolymers of carbon monoxide and one or more ethylenically unsaturated compounds by reacting the monomers under polymerization conditions in the presence of a catalyst system comprising:
- a) a source of cations of one or more metals of Group VIII of the Periodic Table, and
- b) a source of anions, in the further presence of a diluent in which the copolymers are insoluble or virtually insoluble and of a minor amount of one or more non-ionic surfactants.
