Lacquers comprising chlorinated indiarubber in solution are stabilized by the addition thereto of a substance comprising an ethylene oxide grouping, in quantity sufficient to combine with the hydrochloric acid split off from the chlorinated rubber. Numerous ethylene oxide derivatives are specified among these being epichlorhydrin, phenoxypropene oxide and its alkyl and chlorine derivatives, dimethylglycide, and phenylmethylglycide acid ethyl-ester. Specification 384,639, [Group IV], is referred to.ALSO:Chlorinated organic substances of high molecular weight are stabilized by the addition thereto of a compound containing an ethylene oxide grouping, in quantity sufficient to combine with the hydrochloric acid split off from the chlorinated substance. Numerous ethylene oxide derivatives are specified, among these being epichlorhydrin, phenoxypropene oxide and its alkyl and chlorine substitution products, dimethylglycide, and phenylmethylglycide acid ethyl-ester. Examples describe the stabilization of chlorinated rubber and solutions thereof for use as lacquer, chlorinated train oil, chlorinated montan wax, and polymerized vinyl chloride.
