Organosilicon compounds and rubber compositions made by using the same

Abstract

An organosilicon compound having a structure represented by following general formula: R1: methyl group or ethyl group, R2: a branched or linear, saturated or unsaturated aliphatic hydrocarbon group having 3 to 8 carbon atoms, n: 0.5˜2.5 (an average composition), R3: a divalent hydrocarbon group of —CH2—, —CH2CH2—, —CH2CH2CH2—, —CH2CH2CH2CH2—, —CH2CH2CH2CH2CH2—, —CH(CH3)—, —CH2CH(CH3)—, —C(CH3)2—, —CH(C2H5)—, —CH2CH2CH(CH3)— or —CH2CH(CH3)CH2—, X: S, S(C═O)—R4, SH or NH(3−p), and R4: a branched or linear, saturated or unsaturated aliphatic hydrocarbon group having 1 to 30 carbon atoms. When X═S, p=2 and m=1˜10. When X═S(C═O)—R4, p=1 and m=1. When X═SH, p=1 and m=1. When X═NH(3−p), p=1˜3 and m=1. The organosilicon compound simultaneously suppresses discharge of volatile alcohols generated during the reaction with an inorganic filler and exhibits great reactivity with the inorganic filler.
