More Information
Summary:This invention is based upon the concept of modifying the surface of silica with a metal, such as titanium or zirconium, which will catalyze silanol condensation reactions on the surface of the silica. The utilization of such metalated silica as a filler in rubber compositions results in improved polymer filler interaction and in turn improved physical properties. For instance, such surface metalated siliceous fillers can be used in tire tread compounds to attain improved rolling resistance and treadwear without compromising traction characteristics. The present invention more specifically discloses a tire having a tread comprising (1) a rubbery polymer, (2) a silica coupling agent, and (3) a surface metalated siliceous filler.
