  • Patent number: 10253163
    Abstract: A polymeric composition includes a diene elastomer; an azodicarboxy compound; and a reinforcing filler comprising silica. The composition is not foamed. A method for preparing a polymeric composition includes mixing in one or more steps: a diene elastomer; an azodicarboxy compound; and a reinforcing filler. The mixing temperature is less than 160° C. in mixing steps in which the azodicarboxy compound is present. In an embodiment, the mixing temperature is kept below the decomposition temperature of the azodicarboxy compound.

  • Patent number: 10023660
    Abstract: Provided herein are organic solvent-based processes for the isolation of purified natural rubber from non-Hevea plants. The processes are particularly useful with plant matter that comprises at least 90% by weight roots sourced from Taraxacum kok-saghyz (Russian dandelion), Scorzonera tau-saghyz (Tau-Saghyz), Scorzonera uzbekistanica, and combinations thereof. Also provided herein is a purified non-Hevea rubber product containing 100 phr of rubber sourced from Taraxacum kok-saghyz, Scorzon-era tau-saghyz, Scorzonera uzbekistanica, and combinations thereof, having a specified purity level. Additionally provided are sulfur-vulcanizable rubber compounds and sulfur-vulcanized rubber compounds that incorporate 10-100 phr of purified non-Hevea rubber product sourced from Taraxacum kok-saghyz, Scorzonera tau-saghyz, Scorzonera uzbekistanica, and combinations thereof, having a specified purity level.

  • Patent number: 9670341
    Abstract: The present disclosure provides reinforcing filler-containing rubber compositions suitable for use in tires, and particularly in tire treads. These rubber compositions comprise a metal carboxylate. The metal carboxylate provides improved processability to the rubber compositions in the form of a reduced Mooney viscosity. In certain exemplary embodiments, these rubber compositions containing the metal carboxylate also have an enhanced elastic modulus (also referred to as the G?). Further, in certain of the enhanced elastic modulus embodiments, the rubber compositions containing the metal carboxylate also have decreased hysteresis loss.
