Abstract
The present invention is directed toward anionic polymerization initiators which are soluble in hydrocarbon solvents. The initiators include a lithio amine having the general formula ALi. The component A is a dialkyl or dicycloalkyl amine radical or a cyclic amine. 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.
