Abstract: The invention is directed to a method of preparing sulfenic acid chlorides and sulfenic acid esters with hydrolyzable silyl groups in which an oligosulfane containing silyl groups is chlorinated, the sulfenic acid chloride produced is separated and converted by reaction with an alkali alcoholate to the corresponding sulfenic acid ester.

Abstract: The invention is directed to the modification of natural oxidic or silicate fillers with water insoluble sulfur containing organosilicon compounds. For this purpose, the fillers are converted into an aqueous suspension and treated with the organosilicon compounds, in a given case in the presence of an emulsifier.

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.
