PROCESS FOR PREPARING POLYMERS BY ANIONIC POLYMERIZATION

摘要

A process for preparing polymers by means of the anionic polymerization of polymerizable monomers comprising contacting one or more anionically polymerizable monomers with an alkalimetal-containing anionic initiator under anionic polymerization condition characterized by terminating the polymerization by contacting the reaction mixture with an inorganic acid selected from sulfuric acid, phosphoric acid and mixtures thereof.
