Sulfur-containing sorbents are produced by copolymerization of vinyl-containing monomers and divinylsilylside. Divinyl sulfide is incorporated in the reaction mixture in an amount of 0.014 to 1.4 moles per mole of vinyl monomer. As the vinyl monomer, acrylonitrile, vinylpyridine, N, N'-pp'-diphenylmethane bismaleimide, or a mixture of vinylpyridine and divinylbenzene at a ratio of 0, From 02 to 0.15 mol of divinylbenzene per mole of vinylpyridine used. The invention is intended for use in various industries, e.g. In hydrometallurgy for the recovery of copper, silver and other metals or in the pharmaceutical industry for the production of streptomycin. |
