  • Publication number: 20190232718
    Abstract: This invention reveals a pneumatic tire comprising 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, and an innerliner which covers the inner surface and which is comprised of a halobutyl rubber, a filler and lignin. The incorporation of lignin into the innerliner prevents migration of moisture into the tire carcass which can lead to corrosion and consequential delamination of steel cords within the tire. Normally the lignin will be included in such innerliner formulations in an amount which is within the range of 1 phr to 20 phr. Lignin can also be used to protect the steel belts by incorporating it into other tire components located between the innerliner and the belts.

  • Publication number: 20120073720
    Abstract: The present invention is based upon the unexpected finding that lignin can be incorporated into wire coat stock composition to improve metal to rubber adhesion. It has been further found that lignin can be used as a replacement in whole or in part for conventional rubber-to-metal adhesion promoters, such as cobalt materials which are conventionally used in wire coat stocks to attain and maintain needed rubber-to-wire adhesion properties. In fact, wire coat stocks that contain lignin provide more that adequate rubber-to-metal adhesion characteristics for typical applications, such as in tires, and maintain needed levels of adhesion over long periods of product service. For instance, high levels of rubber-to-metal adhesion are maintained under harsh conditions, such as exposure to elevated temperatures and high levels of humidity.

  • Patent number: 7906682
    Abstract: This invention discloses a process for making dilithium initiators in high purity. This process can be conducted in the absence of amines which is desirable since amines can act as modifiers for anionic polymerizations. The dilithium compounds made are highly desirable because they are soluble in aromatic solvents.
