ABSTRACT:
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. In other words, modifying the surface of silica with titanium or zirconium provides a catalyst for the silanol condensation reaction between the silica surface and silane coupling agents used in silica filled compounds. 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 an elastomeric composition which is comprised of (1) a rubbery polymer, (2) a silica coupling agent, and (3) a surface metalated siliceous filler. The subject invention further reveals a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads, wherein said tread is adapted to be ground-contacting, and wherein said tread is comprised of (1) a rubbery polymer, (2) a silica coupling agent, and (3) a surface metalated siliceous filler.
