Abstract: Compositions comprising polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are stabilized against degradation caused by exposure to ultra violet light by intimately mixing therewith a stabilizing quantity of certain organic stabilizers. These certain stabilizers are hydroxybenzophenones, hydrobenzotriazoles, diphenylamines and aniline substituted triazines.

Abstract: A closable thermoplastic container for holding or conveying liquid hydrocarbon fuels and organic solvents, characterized in that at least those parts of said container which will come in contact with the liquid hydrocarbon fuels and organic solvents, is based on copolymers of CO or SO.sub.2, which polymers have been prepared by polymerization of CO or SO.sub.2 with at least one olefinically unsaturated compound A, and which polymers are made up of units --CO--(A')-- respectively --SO.sub.2 --(A')-- and in such a manner that the adjacent --CO-- respectively --SO.sub.2 -- units are separated by a single unit A', wherein the, or each, A' represents a monomer unit originating a compound A.

Abstract: A structural adhesive consisting of:a linear alternating copolymer or interpolymer consisting of carbon monoxide and at least one ethylenically unsaturated hydrocarbon.

Abstract: The invention is a linear random terpolymer comprised of repeating units of --CO--(C.sub.2 H.sub.4)-- and units of --CO--(C.sub.x H.sub.y)-- where x is greater than 2 and less than 20, having a melting point between about 150.degree. C. and about 245.degree. C. The invention also concerns a process to prepare a polymer having a melting point less than about 245.degree. C. which comprises contacting carbon monoxide and ethylene in the presence of one or more hydrocarbons C.sub.x H.sub.y containing an olefinically unsaturated --CH.dbd.CH-- group, where x is greater than 2 and less than 20, with a suitable catalyst and under conditions effective to prepare a linear random polymer having units of the formula --CO--(C.sub.2 H.sub.4)-- and units of the general formula --CO--(C.sub.x H.sub.y)--, and having a melting point less than about 245.degree. C.
