Zusammenfassung: | 129,826. Peachey, S. J. July 26, 1918. Vulcanizing by cold method; vulcanizing-materials.-India-rubber is vulcanized in the cold by alternate treatment with sulphur dioxide and hydrogen sulphide, the two gases yielding sulphur within the substance of the rubber. A solution of hydrogen sulphide in benzene may be used instead of the gas after treatment with sulphur dioxide. The process may be used for the vulcanization of rubber dissolved in a solvent such as benzene. Sulphur dioxide is passed into the solution, hydrogen sulphide is passed into a second solution, and the two solutions mixed; or one of the gases may be in solution in benzine. |
