    Abstract: 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.

    Abstract: The present invention is directed toward anionic 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.

    Abstract: Novel silicon-containing derivatives of crystalline, high-trans-1,4 polybutadiene in which organosilicon-containing groups are bonded to the 1,2-vinyl carbon atoms along the main chain of the butadiene polymers through the carbon-silicon linkages. These derivatives of butadiene polymers are produced by the addition reaction of an organosilicon compound having one hydrogen atom directly bonded to the silicon atom in the molecule to the double bonds in the 1,2-vinyl group butadiene polymers. These derivatives having good compatibility with siliceous fillers and when blended with filled diene rubbers are cured to elastomer compositions having excellent properties suitable for the production of tires.
