Abstract
It has been unexpected found that silylated triglyceride oils can be incorporated into tire tread rubber formulations that include reinforcing fillers to provide improved wet traction characteristic, rolling resistance, and tread-wear without compromising cured stiffness (dry traction) and ultimate properties (chip/chunk resistance). The level of silica coupling agent needed in such formulation can also typically reduced. The present invention more specifically discloses a rubber formulation which is comprised of (1) a rubbery polymer; (2) a reinforcing filler, such as silica or carbon black; and (3) a silylated triglyceride oil. The silylated triglyceride oil will include silyl groups of the structural formula: —(CH)—Si(OR), wherein n represents an integer within the range of 1 to 8, and wherein R represents an alkyl group containing from 1 to 8 carbon atoms.
