Method for reducing the aliphatic halide content of epoxy resins using a
solvent mixture including a polar aprotic 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.
