Beschreibung
Zusammenfassung:	Thermoplastic moulding materials (M) comprise a two-phase matrix (A) and a homogeneous distribution of at least 30 vol.% permanently magnetic or magnetisible metal compound and/or metal alloy filler (B). (A) comprises the following components : (A1) 70-99 wt.% partially aromatic copolyamide with a m.pt. greater than 280 degrees C and an aliphatic dicarboxylic acid content less than 50 mol.% (with respect to all acid monomers) ; (A2) 1-30 wt.% aliphatic (co)polyamide containing at least 10 -CH2- groups per -CONH- group ; and (A3) 0-10 wt.% additives affecting properties and/or processing. Also claimed are (i) the preparation of (M) and (ii) the use of (M) for the preparation of moulded articles.
