Abstract
An initiator for the anionic polymerization of heterocyclic 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 alcohol, a secondary or tertiary alcohol, an ether alcohol, an amino alcohol, a polyether alcohol, a polyamino alcohol, a polyaminoetheralcohol, or an enol from a ketone.
