Abstract: The above described deficiencies and drawbacks are overcome by the process for making poly(arylene ether)-polyamide compositions which comprise about 10 weight percent (wt %) to about 90 wt % poly(arylene ether), about 90 wt % to about 10 wt % polyamide, about 0.01 wt % to about 10 wt % compatibility modifier, and optionally other additives known in the art. The process comprises several components which can be employed singly or in combination, namely: utilizing resins and additives that are substantially free of gaseous oxygen (air-free; e.g. less than about 1.0 vol % oxygen preferred, and less than about 0.5 vol % oxygen especially preferred, and less than about 0.05 vol % especially preferred); melting and compounding under an atmosphere which is substantially air-free; adding up to 20 wt % of polyamide to the poly(arylene ether) before compounding; when employing an extruder with an atmospheric vent, operating with the atmospheric vent open; and performing the injection molding under an inert atmosphere.

Abstract: A method for electrostatic painting (coating) of a non-conductive polymer surface is disclosed, comprising applying a conductive layer on or adjacent to all or part of a side opposite the non-conductive polymer surface to be painted so as to provide sufficient conductivity to enable electrostatic painting of the non-conductive polymer surface. With the conductive layer in place the article can then be painted electrostatically. After painting, the conductive layer can optionally be removed without affecting the painted surface.

Abstract: A thermoplastic composition comprising a poly(arylene ether), a polyamide, a compatibilizing agent, and a polyester ionomer exhibits reduced moisture absorption and improved paint adhesion. Use of the polyester ionomer allows use of lower amounts of conductive fillers.
