Abstract

THE TOTAL HALIDE CONTENT OF EPOXY RESINS IS REDUCED BY HEATING A RESIN CONTAINING HALIDE DISSOLVED IN A SOLVENT MIXTURE CONTAINING AT LEAST ONE KETONE, AT LEAST ONE AROMATIC HYDROCARBON AND OPTIONALLY AT LEAST ONE COMPOUND CONTAINING AT LEAST ONE ALIPHATIC HYDROXYL GROUP IN THE PRESENCE OF AN ALKALI METAL HYDROXIDE FOR A TIME SUFFICIENT TO REDUCE THE TOTAL HALIDE CONTENT.
