METHOD FOR PRODUCING THIOESTER GROUP-CONTAINING ORGANOSILICON COMPOUND, THIOESTER GROUP-CONTAINING ORGANOSILICON COMPOUND, COMPOUNDING AGENT FOR RUBBER, RUBBER COMPOSITION, AND TIRE

摘要

PROBLEM TO BE SOLVED: To provide: a new method for producing a thioester group-containing organosilicon compound by a convenient reaction with dramatically improved working efficiency and generating a reduced byproduct; an organosilicon compound having a hydrolyzable silyl group, a thioester group and a carboxy group in the same molecule, remarkably reducing hysteresis loss of the cured rubber composition; a compounding agent for rubber including such the organosilicon compound; a rubber composition prepared by blending such the compounding agent for rubber; and a tire produced by using the cured rubber composition.;SOLUTION: There are provided the organosilicon compound having the hydrolyzable silyl group, the thioester group and the carboxy group in the same molecule, and a new method for producing a thioester group-containing organosilicon compound via a reaction of an organosilicon compound having a hydrolyzable silyl group and a mercapto group with a carboxylic anhydride.;COPYRIGHT: (C)2013,JPO&INPIT
