Abstract

Ethylenically unsaturated monomers are polymerized with an anionic initiator by adding the initiator portionwise to a stirred polymerizing mixture throughout the course of reaction and effecting the additions only when the temperature of the reactants falls below that temperature at which the effectiveness of the initiator is decreased to one half in 15 minutes or less under the conditions of the reaction. The reaction may be carried out in bulk or in a diluent, and may be terminated at any desired degree of conversion. Exemplified initiators are tert.-butyl lithium, potassium tert.-butyl alcoholate, lithium tert.-butyl alcoholate, sodium tert.-butyl alcoholate, and triphenylmethyl sodium. Exemplified monomers are methyl methacrylate, butyl methacrylate, methyl acrylate, butyl acrylate and acrylonitrile. The Specification includes a drawing of a suitable reactor.
