ABSTRACT OF THE DISCLOSURE The present invention is directed toward anionic polymerization employing lithio aldimines mixed with an organic alkali metal randomizer compound and optionally, a chelating reagent. The lithio aldimines have the general formula (A)Li, where A is derived from a substituted aldimine. 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 a substituted aldimine and an organolithium compound. The resulting polymers may be modified with a terminating, coupling or linking agent, which may provide the polymer with a multifunctionality.
