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.
