ORGANOSILICON COMPOUND, MIXTURE OF ORGANOSILICON COMPOUND AND METHOD FOR PRODUCING SAME, RUBBER COMPOSITION CONTAINING MIXTURE OF ORGANOSILICON COMPOUND, AND TIRE

WIPO Patent Application WO/2021/053981

A1

A mixture of an organosilicon compound represented by average structural formula (2), wherein the area percentage occupied by an organic compound represented by structural formula (1) in GPC is from 5% to 95%, provides a rubber composition which exhibits excellent dispersibility of an inorganic filler and enables the achievement of a crosslinked cured product that has improved wear resistance, rolling resistance and wet grip performance. This rubber composition enables the achievement of a desired low fuel consumption tire.　(2): (R1O)3-p(R2O)pSi-(CH2)j-Sy-(CH2)k-Si(OR2)q(OR1)3-q (In the formula, R1 represents an alkyl group having from 1 to 3 carbon atoms; R2 represents an alkyl group having from 4 to 8 carbon atoms; p represents a number from 0 to 3; q represents a number from 0 to 3; j represents a number from 1 to 10; k represents a number from 1 to 10; and y represents a number from 2 to 8.)　(1): (R1O)3-m(R2O)mSi-(CH2)h-Sx-(CH2)i-Si(OR2)n(OR1)3-n (In the formula, R1 and R2 are as defined above; m represents an integer from 0 to 3; n represents an integer from 0 to 3; h represents an integer from 1 to 10; i represents an integer from 1 to 10; x represents an integer from 2 to 8; and (m + n) represents an integer from 3 to 6.)
