Abstract

863,205. Treating synthetic rubber latices. UNITED STATES RUBBER CO. Sept. 29, 1959 [Nov. 28, 1958], No. 32983/59. Class 2(6). The size of dispersed polymer particles in a butadiene polymer synthetic rubber latex are increased by adding to the latex 0À2 to 8 % of an alkali salt electrolyte and 0.01 to 1 % of polyvinyl methyl ether. Specified latices are those of polymers of butadiene, isoprene, piperylene, 2, 3-dimethyl-butadiene and their mixtures or of their copolymers with styrene, vinyl toluene, α - methylstyrene, chlorostyrene, dichlorostyrene, vinyl naphthalene, acrylic acid, methyl acrylate, methyl methacrylate, acrylonitrile, methacrylnitrile, methacrylamide, 2-vinyl pyridine, 2-methyl- 5-vinylpyridine, methylvinylketone, and vinylidene chloride. The alkali salt electrolyte may be sodium sulphate, potassium sulphate or an ammonium salt of carbonic acid.
