Abstract: Very desirable polyfunctional lithium containing polymerization initiators are prepared by reacting an adduct of an organo lithium compound and styrene with an organic compound containing at least two 1,1-diphenylethylene groups in the proportion of about two moles of the adduct to one mole of the organic compound. A difunctional lithium initiator is prepared thereby. The difunctional initiator may be reacted with styrene and subsequently an additional quantity of the diphenylethylene compound which in turn is reacted with the styrene-organo lithium adduct to form a trifunctional initiator. The process can be repeated to obtain an initiator having any desired degree of lithium functionality. 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 and preparation of block copolymers.

Abstract: Polymerizable monomers are polymerized in a reaction mixture containing as catalysts (A) an oxygen source and (B) an organic boron compound which is soluble in the reaction mixture, the boron compound being (1) a diborane adduct wherein the boron atoms are linked by a hydrocarbyl group having an aliphatic carbon atom bonded to at least one of the boron atoms, or (2) oligomers based on repeating units containing at least two boron atoms linked by hydrocarbyl groups having an aliphatic carbon atom bonded to at least one of the boron atoms. The diborane adducts include the adduct of borane or a dialkylborane and 1,3-butadiene. The oligomers include polymers of diborane/propadiene adducts. The organoboron catalysts provide rapid initiation of polymerization and the polymerization is relatively insensitive to oxygen concentration, thereby permitting polymerization at ambient temperatures.

Abstract: Alkali metal organic compounds including perlithiated organic compounds are produced by contacting an organic compound having a carbon to hydrogen bond or a carbon to halogen bond in its molecular structure or carbon vapor with a vaporous alkali metal under dry conditions and in the absence of a gas that reacts with the alkali metal other than the organic compound. The alkali metal is activated such as thermally or by being passed through a radio frequency field so that it has sufficient energy to break at least one of the bonds. Perlithiated compounds are formed from alkanes, alkenes, cycloalkanes and aromatic hydrocarbons.

Abstract: An alkali metal-containing, organometallic product, which is hydrocarbon-soluble, is prepared by reacting an organo-alkali metal reactant in which the alkali metal atom is bonded to a carbon atom, e.g. cyclohexyl-lithium, with a di(organooxy)-alkaline earth metal reactant, e.g. di-n-butoxy-magnesium, in an organic solvent at about -20.degree. to +120.degree.C. The organo-alkali metal reactant can be prepared by reacting an organo halide with an alkali metal, and this can be done in situ, i.e. in the presence of the di(organooxy)-alkaline earth metal reactant. The organometallic product has approximately the same chemical reactivity as the organo-alkali metal reactant from which it is prepared, but is more soluble in hydrocarbon solvents.
