Abstract: There is prepared a homogeneous mixture of 95 to 30% carbon black and 5 to 70% resorcinol. The resorcinol preferably either has an average particle size of 0.01 to 0.4 mm or is broken down to that size. The product is employed in rubber mixture to improve the adhesion of rubber vulcanizates to metal, textile fibers, glass fibers, or their structures.

Abstract: Novel bis-(silylethyl)-oligosulphides are obtained by reacting a vinyl silane of the formula (CH2=CH)m-SiRn1R4-(m+n) in which R represents chlorine, bromine, iodine, C1-C3-alkoxy, 2-methoxyethoxy, 2-ethoxyethoxy or hydroxy, R1 represents C1-C3-alkyl, phenyl or C5-C7-cycloalkyl, n is 0, 1 or 2, m is 1 or 2 and m+n is 1, 2 or 3 with sulphur as well as in a given case hydrogen sulphide in molar ratios of vinyl silane to sulphur of from 1:2.5 to 1:10 and vinyl silane to hydrogen sulphide of from 1:0 to 1:5 at temperatures between about 100 DEG and 200 DEG C. under pressure of from 1 to 25 bars (total pressure at the reaction) temperature) and in the presence of sulphidation catalysts known per se, in a given case followed by hydrolysis or partial hydrolysis of the reaction products. The bis-(silylethyl)-oligosulphides are used as reinforcing additives (adhesive agents) in crosslinkable rubber mixtures containing silicate fillers and in a given case carbon black as well as in a given case sulphur and other customary constituents.
