Extrudable thermoplastic composition comprising a compatibilized polyphenylene ether polyamide resin blend

摘要

The present invention deals with an extrudable thermoplastic composition comprising a compatibilized polyphenylene ether-polyamide resin blend. By using a polyphenylene ether with an intrinsic viscosity of more than 45 ml/g as measurred in toluene at 25 degrees C. and a concentration of 0.6 gram per 100 ml and a polyamide with a reduced viscosity of more than 175 ml/g as measured in sulphuric acid in accordance with ISO 307, it proved to be possible to obtain a blend which could be extruded without difficulties. Blends in which only one of the two resins i.e. the polyphenylene ether or the polyamide possessed the required viscosity values were less suitable for processing by extrusion. The composition may further comprise other usual additives.
