Document Type and Number:
WIPO Patent Application WO/2021/166396
Kind Code:
A1
Abstract:
An organopolysiloxane represented by average empirical formula (1), which gives a rubber composition that renders desired fuel-saving tires possible, the tires being excellent in terms of hardness, tensile property, rolling resistance, and wet gripping. Formula (1): (R1)a(R2)b(OR3)c(R4)dSiO(4-2a-b-c-d)/2 (In the formula, the R1 moieties each independently represent a divalent organic group containing a sulfide group, the R2 moieties each independently represent an aryl group having 6-10 carbon atoms or an aralkyl group having 7-10 carbon atoms, the R3 moieties each independently represent a hydrogen atom, an alkyl group having 1-20 carbon atoms, an aryl group having 6-10 carbon atoms, an aralkyl group having 7-10 carbon atoms, or an alkenyl group having 2-10 carbon atoms, the R4 moieties each independently represent an alkyl group having 1-12 carbon atoms, and a, b, c, and d indicate numbers satisfying 0<2a<1, 0
