Beschreibung
Zusammenfassung:	Solvent-resistanct resin blends are prepared from a polyphenylene ether, or blend thereof with a polystyrene, a linear polyester such as a poly(alkylene dicarboxylate) and at least one polymer containing a substantial proportion of aromatic polycarbonate units as a compatibilizing agent. There may also be present a minor amount of at least one epoxide and/or masked isocyanate such as triglycidyl isocyanurate or a glycidyl methacrylate polymer. The polyphenylene ether is preferably inactivated by reaction with at least one non-volatile carboxylic acid or anhydride and/or by extrusion with vacuum venting.
