Abstract
The resistance to discoloring of formed articles from polymer mixtures which comprise a polyphenylene ether and at least a second polymer can be improved by treating the surface of the formed articles with a solvent. The solvent is chosen so that the polyphenylene ether does dissolve therein, but the second polymer does not dissolve therein.
