TITLE PROCESS FOR MAKING FOAMED, SULFUR-CURED POLYMER BLEND COMPOSITIONS ABSTRACT OF THE DISCLOSURE A blend of an E/X/Y copolymer, where E is ethylene, X is a vinyl ester, and Y is carbon monoxide or sulfur dioxide, with a polymer of vinyl halide or vinylidene halide is foamed and cured by dispersing in the blend a blowing agent and sulfur or a sulfur-releasing agent and heating the blend containing those additives at 100-180°C for a sufficient time to produce curing and foaming. This process can be run either continuously or batchwise in conventional equipment under conventional conditions in the presence of air. Plasticizers and other materials which often interfere with peroxide cures can be present in the process of this invention. The foamed and cured products have excellent physical properties and ozone resistance.
