Abstract: Thermoplastic moulding compsn. contains 35-92 (wt.% thermoplastic polymer (I), 5-35% polymer (II) contg. imide gps. and 3035% fibrous reinforcement (III). The compsn. pref. contains 40-80% (I), 10-35% (II) and 10-30% (III). USE/ADVANTAGE - The compsn. is used for making fibres, films and mouldings, (claimed). It has good mechanical properties, very good surface quality and high scratch resistance. Compsns. are useful e.g. in the automobile and building fields and for making housings for electrical equipment.
