SULFUR-CONTAINING ORGANIC SILICON PRODUCT, PRODUCTION METHOD THEREOF, AND RUBBER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide: a sulfur-containing organic silicon product that exhibits viscosity decline and low rolling resistance of a rubber compound and further exhibits excellent ordinary physical properties by being blended to a rubber composition; a production method thereof; and a rubber composition containing the sulfur-containing organic silicon product.SOLUTION: A sulfur-containing organic silicon product is obtainable by reacting an organic silicon compound and a sulfating agent represented by sulfur. The organic silicon compound contains a terpene residue containing a double bond represented by limonene, and a group bonded to an inorganic filler represented by 3-mercaptopropyltriethoxysilane. A method of producing the sulfur-containing organic silicone product, and a rubber composition containing the sulfur-containing organic silicon product are also provided.
