Abstract

Flame-retardant, thermoplastic molding materials containing PA0 A) at least one polyphenylene ether, PA0 B) at least one vinylaromatic polymer and PA0 C) at least one flameproofing agent, comprise PA0 D) an amount of expandable graphite which increases the resistance of the molding material to dripping and are used for the production of flame-retardant moldings, fibers and films.
