| 20080295936 | ELASTOMERS CONTAINING SURFACE METALATED SILICEOUS FILLERS - 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. | 12-04-2008 |
| 20090078354 | Rubber Formulation with Adhesive-Compatible Surface - A method of effecting an improved adhesive bond between a rubber surface and a device adhered thereto is disclosed. In pneumatic tires, monitoring devices are more securely adhered to the innerliner of the tire utilizing a room temperature vulcanizable adhesive wherein curing is facilitated in the presence of moisture. The innerliner formulation is prepared by incorporating a material which has incomplete compatibility with the rubber of the innerliner formulation, and which has hygroscopic properties which thereby tends to attract moisture. | 03-26-2009 |
| 20090151846 | TIRE WITH INNERLINER CONTAINING LOW MELTING POLYAMIDE - The present invention is directed to a pneumatic tire comprising a carcass and an innerliner in direct contact with the carcass, the innerliner comprising a rubber composition comprising:

| 20100204368 | FUNCTIONALIZED LIGNIN, RUBBER CONTAINING FUNCTIONALIZED LIGNIN AND PRODUCTS CONTAINING SUCH RUBBER COMPOSITION - The invention relates to functionalized lignin, rubber compositions which contain functionalized lignin and to products which have at least one component comprised of such rubber composition. | 08-12-2010 |
| 20110009546 | SPECIALIZED SILICA, RUBBER COMPOSITION CONTAINING SPECIALIZED SILICA AND PRODUCTS WITH COMPONENT THEREOF - The invention relates to allyl functionalized precipitated silica, rubber compositions containing such silica, particularly sulfur cured rubber compositions, and articles of manufacture having a component thereof such as, for example tires. The invention particularly relates to synthetic amorphous silica, particularly a precipitated silica, treated with an allyl silane, particularly to a precipitated silica containing allyl functional groups. | 01-13-2011 |
| 20110060083 | SPECIALIZED SILICA, RUBBER COMPOSITION CONTAINING SPECIALIZED SILICA AND PRODUCTS WITH COMPONENT THEREOF - The invention relates to allyl functionalized precipitated silica, rubber compositions containing such silica, particularly sulfur cured rubber compositions, and articles of manufacture having a component thereof such as, for example tires. The invention particularly relates to synthetic amorphous silica, particularly a precipitated silica, treated with an allyl silane, particularly to a precipitated silica containing allyl functional groups. | 03-10-2011 |
| 20110136969 | RUBBER COMPOSITION CONTAINING SILICA REINFORCEMENT AND FUNCTIONALIZED CROSSLINKS AND PRODUCTS WITH COMPONENT THEREOF - The invention relates to a rubber composition which contains silica reinforcement and functionalized crosslinks, particularly crosslinked functionalized precipitated silica, including sulfur crosslinked functionalized silica and associated cured rubber compositions, and to articles of manufacture having a component thereof such as, for example tires. A dimercaptothiadiazole is used to form the crosslinked network within the rubber composition. The mercapto moieties of said dimercaptothiadiazole are desirably protected from prematurely reacting with, for example, diene-based elastomers and sulfur-containing silica coupling agents by pre-reaction with an aromatic carboxylic acid chloride or by reacting in situ with an aromatic carboxylic acid | 06-09-2011 |
| 20110146859 | TIRE WITH COMPONENT CONTAINING CARBON NANOTUBES - The present invention is directed to a method of conducting static electricity in a pneumatic tire, comprising the steps of mixing a rubber compound comprising at least one diene based rubber, from 60 to 150 phr of precipitated silica, less than 40 phr of carbon black, and from 1 to 10 phr of carbon nanotubes having a length of at least 5 microns; forming a tire tread from the rubber compound; and including the tire tread in the tire; wherein the volume resistivity of the tire tread is less than 1×10 | 06-23-2011 |
