Abstract
The present invention deals with a thermoplastic composition comprising (a) a compatibilized polyphenylene ether-polyamide base resin, and (b) 1-7 parts by weight per 100 parts by weight of (a) of an electroconductive carbon black, with an Izod notched impact strength of more than 15 kJ/m.sup.2 and a volume resistivity of less than 10.sup.6 Ohm.cm. The compositions of the invention are suitable for molding objects which can easily be painted by an electrostatic coating process. The invention further provides a process for the preparation of the composition of the invention comprising at least two steps. In the first step the base resin is formed. In a further step the carbon black is incorporated in the base resin. The invention further relates to articles formed out of the composition of the invention and to such articles which have been painted by an electrostatic coating process.
