| 20110094645 | Innerliners for Off-Road, Farm, Large Truck and Aircraft Tires - Disclosed is a pneumatic tire comprising an innerliner comprising a functionalized poly(isobutylene-co-p-methylstyrene) elastomer, at least one layered filler; and less than 8 phr of at least one processing aid; wherein the innerliner possesses a permeation coefficient of less than 200 mm·cm | 04-28-2011 |
| 20110098405 | Elastomer Nanocomposites With Incorporated Process Oils - This disclosure is directed to nanocomposite compositions that are suitable for air bladders, innertubes, innerliners and other desirable air-retention articles. In particular, this disclosure is directed to compositions that include the nanocomposite, the nanocomposite made in such that its air-retention properties are much improved over what is known, while maintaining desirable elasticity and processability. In a particular aspect, an air-retention article such as an innerliner if formed by first contacting a desirable elastomer, especially a functionalized poly(isobutylene-co-p-methylstyrene) elastomer, with one or more layered fillers such as a clay described further below, and also contacting one or more processing aids, and one or more solvents to form an nanocomposite composition. The nanocomposite composition is then precipitated to form the solid nanocomposite composition which can be dried and further blended with other suitable ingredients such as, for example, curative agents, thus forming an innerliner suitable for a tire or other article. | 04-28-2011 |
| 20110152422 | Elastomeric Nanocomposites, Nanocomposite Compositions, and Methods of Manufacture - A nanocomposite is formed from at least one copolymer and at least one nanofiller. The copolymer is formed of units derived from isoolefins having from 4 to 7 carbon atoms and multiolefins. The nanofiller comprising a surfactant wherein the surfactant has the structure of (R | 06-23-2011 |
| 20110169199 | Process For Preparing Articles - The present invention relates to a process for preparing a thermoplastic vulcanizate (TPV) comprising: contacting a thermoplastic polymer, a cross-linkable elastomer, at least one curative, and at least one cure activator in a solvent to form Composition A. The solvent is then removed, and thereafter the cross-linkable elastomer is at least partially cured. The average particle size of the cross-linkable elastomer is 10 microns or less after the solvent is removed. | 07-14-2011 |
