Abstract
A rubber composition which contains (A) an organosilicon compound represented by formula (1) and gives a cured object satisfying desired fuel (or power)-saving tire properties. (R1 represents an alkyl or aryl group, R2 represents an alkyl or aryl group, e, f, and g each indicate a number larger than 0 and satisfy g/(e+f+g)<0.05, and m is an integer of 1-3.)
Claims9
A rubber composition comprising (A) an organosilicon compound, (B) a diene rubber, (C) a filler, and (D) a sulfur-containing organosilicon compound;
- (A) the organosilicon compound having the formula (1):
- wherein R1 is each independently a C1-C10 alkyl group or C6-C10 aryl group, R2 is each independently a C1-C10 alkyl group or C6-C10 aryl group, e, f, and g e and f are each independently a number of 1 to 500, g is a number of 0.1 to 10, g/(e+f+g) is a number of 0.01 or more and less than 0.05, (f+g)/(e+f+g) is a number of 0.28 or more and up to 0.6, and m is an integer of 1 to 3, with the proviso that the arrangement of individual repeat units is arbitrary.
