MODERATION OF MANGANESE CHELATE CATALYZED POLYMERIZATION OF PHENOLIC MONOMERS

摘要

A novel process is disclosed for the moderation of the manganese chelate catalyzed oxidative coupling of a phenolic monomer. The process is based on the addition to the polymerization mixture of a quantity of a polyfunctional alkanolamine that is sufficient to retard the rate of polymerization and permit precise control of the polymerization reaction.
