Claims13
A method of processing a rubber composition comprising mixing
- (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 R2 are individually selected from the group consisting of
- wherein R3, R4 and R5 are individually selected from the group consisting of alkyls having from 1 to 4 carbon atoms;
- R6 is individually selected from the group consisting of from alkyls having 1 or 4 carbon atoms;
- w is an integer of from 30 to 1000, 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.
