摘要： Epoxy resins which are relatively low in total bound halide are prepared by concurrently and continuously adding a mixture of (1) a mixture of an epihalohydrin, a compound containing an average of more than one group reactive with a vicinal epoxide group and a solvent and (2) an aqueous or organic solution of an alkali or alkaline earth metal hydroxide; to (3) a mixture of epihalohydrin and a solvent.

摘要： The total halide content of epoxy resins is reduced by heating a resin containing undesirable halide dissolved in a solvent mixture containing at least one polar aprotic solvent in the presence of an alkali metal hydroxide for a time sufficient to reduce the total halide content.
