  • Elastomer nanocomposites with incorporated process oils
    Patent number: 9475910
    Abstract: 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.
    Type: Grant
    Filed: October 26, 2009
    Date of Patent: October 25, 2016
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Weiqing Weng, Bharat Bhushan Sharma, Michael Brendan Rodgers
  • Blend partner with natural rubber for elastomeric compounds
    Patent number: 8609760
    Abstract: Natural rubber blends, methods for making the same, and articles made therefrom are provided. The natural rubber blend includes at least one propylene copolymer containing ethylene derived units. The natural rubber blend can further include one or more reinforcing fillers, such as carbon black. The presence of the propylene copolymer significantly improves the ozone resistance and ageing properties of the natural rubber gum stock.
