ABSTRACT:
The present invention is directed toward artionic polymerization employing lithio amines mixed with an organic alkali metal compound and optionally, a chelating reagent. The lithio amines have the general formula (A)Li(SOL)y, where SOL is a solubilizing component, A is an alkyl, dialkyl, cycloalkyl or dicycloalkyl amine radical or a cyclic amine, and y is 0 or is from about 0.5 to about 3. The invention is also directed toward polymers and other products made using the initiator, and methods therefor. Further, the invention contemplates a polymer, a polymer composition and products therefrom, which include a functional group from the reaction product of an amine and an organolithium compound. The resulting polymers may be terminated with a terminating, coupling or linking agent, which may provide the polymer with a multifunctionality.
