ABSTRACT:
An initiator for the anionic polymerization of vinyl monomers and dienic monomers comprises the product from the association of an alkali metal amide and the salt from at least one hydroxylated compound with the same alkali metal in an aprotic solvent. The hydroxylated compound is a primary, secondary, or tertiary alcohol. The hydroxylated compound may be a member selected from the group consisting of an alcohol substituted by an heterocyclic group, alcohols containing ethylenic unsaturation, alcohols substituted by an aromatic group, alicyclic alcohols, aromatic alcohols, polyhydroxy compounds, ether-alcohols, polyether-alcohols, and enols from ketones and amino acids.
