Abstract: Highly desirable multifunctional lithium containing initiators are prepared by reacting a compound such as an organo lithium with an organic compound containing at least two 1,1-diphenylethylene groups. 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. Several di-lithium compounds have been employed to initiate polymerization of various unsaturated organic monomers.
