  • Syndiotactic 1,2-polybutadiene latex
    Patent number: 5021381
    Abstract: This invention reveals a technique for preparing syndiotactic 1,2-polybutadiene latex. It more specifically discloses a process for synthesizing syndiotactic 1,2-polybutadiene latex by polymerizing 1,3-butadiene in an aqueous medium in the presence of (1) at least one emulsifier, (2) a catalyst emulsion composition which is prepared by a microfluidization or microemulsification process, and (3) at least one member selected from the group consisting of carbon disulfide and phenyl isothiocyanate. Such syndiotactic 1,2-polybutadiene latices can be utilized in preparing blends of syndiotactic 1,2-polybutadiene with rubbers which are prepared by emulsion polymerization.
    Type: Grant
    Filed: November 13, 1989
    Date of Patent: June 4, 1991
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Gary L. Burroway, George F. Magoun, Ramesh N. Gujarathi
