  • Soluble multifunctional lithium containing initiator
    Patent number: 4196154
    Abstract: Highly desirable organic liquid soluble multifunctional lithium containing initiators are prepared by reacting an organo lithium compound with an organic compound containing at least one group of the configuration 1,3-bis(1-phenylethenyl)benzene. Such initiators can be prepared in the absence of polar solvents and are very desirable for the polymerization of dienes such as butadiene to a desirable 1,4 configuration.
    Type: Grant
    Filed: August 7, 1978
    Date of Patent: April 1, 1980
    Assignee: The Dow Chemical Company
    Inventors: Lu H. Tung, Grace Y-S. Lo, Douglas E. Beyer
  • Soluble multifunctional lithium containing initiator
    Patent number: 4172190
    Abstract: Highly desirable organic liquid soluble multifunctional lithium containing initiators are prepared by reacting on organo lithium compound with an organic compound containing at least one group of the configuration 1,3-bis(1-phenylethenyl)benzene. Such initiators can be prepared in the absence of polar solvents and are very desirable for the polymerization of dienes such as butadiene to a desirable 1,4 configuration.
