Abstract

504,684. Vulcanizing rubber; salts of amines. WINGFOOT CORPORATION. June 17, 1938, No. 18025. Convention date, Sept. 24, 1937. [Class 70] [Also in Group IV] A vulcanization accelerator for rubber consists of a thiazole type accelerator and a guanidine salt of a dithiocarbamic acid derived from a primary amine. Thus, 21À1 parts of symmetrical diphenyl guanidine and 10À7 parts of benzylamine were stirred into 75 parts of benzene. To this mixture were added 7À6 parts of carbon bisulphide. An additive guanidine salt of the formula was formed. This substance was added with 2-mercaptobenzthiazole to a mixture of smoked sheet rubber, zinc oxide and sulphur, to accelerate the vulcanization. Other guanidine accelerators of general formula S # in which RNH-C-S- denotes a dithiocarbamate residue of a dithiocarbamic acid derived from a primary amine RNH2, and X denotes hydrogen, alkyl, aryl or aralkyl. U.S.A. Specifications 1,546,876, 1,672,548, and 1,698,569 are referred to.
