  • Emulsion styrene-butadiene rubber
    Patent number: 6512053
    Abstract: This invention discloses an emulsion styrene-butadiene rubber (SBR) that can be employed in manufacturing tire tread formulations that have rolling resistance and treadwear characteristics that are similar to those made with solution SBR but with improved traction characteristics. Thus, the emulsion SBR of this invention is superior in many respects for use in tire tread compounds to conventional solution SBR and conventional emulsion SBR. This invention more specifically discloses a styrene-butadiene rubber composition which is comprised of repeat units which are derived from styrene, 1,3-butadiene, and a hydroxy alkyl acrylate monomer, wherein the styrene-butadiene rubber composition has a number average molecular weight as determined by field flow fractionation which is within the range of about 50,000 to 150,000, and wherein the styrene-butadiene rubber has a light scattering to refractive index ratio which is within the range of 1.8 to 3.9.
    Type: Grant
    Filed: June 20, 2002
    Date of Patent: January 28, 2003
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Howard Allen Colvin, Michael Leslie Senyek, Jr.
