Abstract

Thermoplastic molding materials based on polyphenylene ethers and nylons are prepared in an extruder by a continuous process in which a modified polyphenylene ether is prepared in a first zone of the extruder and is then mixed with nylons and, if required, further additives in one or more further zones.
