METHOD TO REDUCE THE UNDESIRABLE HALIDE CONTENT OF AN EPOXY RESIN CONTAINING HYDROLYSABLE HALIDE AND ALLOY HALIDE

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.
