Abstract

There is disclosed a rubber composition comprising:(A) 100 parts by weight of at least one rubber containing olefinic unsaturation; and(B) 1.5 to 50 phr of a silicon coupled oligomer of the formula: where R1 and 2 are individually selected from the group consisting of where R3 is selected from the group consisting of alkyls having 1 or 4 carbon atoms; w is an integer of from 9 to 149, x is an integer of from 1 to 100, y is an integer of from 1 to 100, and z is an integer of from 1 to 100 with the proviso that the sum total of x, y and z in each R1 and R2 ranges from 3 to 100.
