Abstract: A process for the preparation of linear alternating copolymers of carbon monoxide and an ethylenically unsaturated compound by polymerizing the monomers in the presence of a suitable catalyst system, one or more components present in the reaction mixture being contaminated with alkali(ne earth) metal salt(s), which process involves a treatment by which at least part of the alkali(ne earth) metal salt is removed such that the total amount of alkali(ne earth) metals present in the copolymerization product is less than 1 part per million by weight; a copolymer composition comprising said copolymer, an alkali(ne earth) metal salt contaminant and a stabilizing quantity of a substance which is able to bind at least part of the alkali(ne earth) metal salt.

Abstract: A melt stabilized copolymer composition comprising a major amount of an alternating copolymer of carbon monoxide with one or more olefinically unsaturated compounds and a minor amount of at least one stabilizing additive which stabilizing additive is a glycidyl ether which comprises per molecule at least one epoxy group and at least one functional group selected from primary alcoholic hydroxy groups and ketonic carbonyl groups. A process for producing the composition and the melt stabilizing agents are also disclosed.

Abstract: Novel thermosetting resins are produced from low molecular weight linear alternating polymers of carbon monoxide and a suitable curing agent. The resin compositions are particularly useful as coatings.

Abstract: Novel thermosetting resin compositions comprise (1) a polyalcohol produced by reduction of a low molecular weight linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and (2) a polyfunctional curing agent. The compositions are cured upon application of heat to cured, crosslinked compositions useful as coatings.
