A thermoplastic moulding compsn. contains (I) 98-70wt.%, w.r.t. (I)+(II), of an at least partially crystalline polyamide, and (II) 2-30% of an aliphatic polycarbonate, unbranched in the C chain. Pref. the polycarbonate has Mn 1000-100,000 (2000-50,000), and is prepd. from a 3-200C aliphatic diol and/or polyether diol. Esp., the polycarbonate is prepd. from 100-1(100-75)wt.% hexane, 1,6-diol and 0-99wt.% of 4-100C oligo- or poly-alkylene glycol. The pref. polycarbonate is polyhexamethylene carbonate or polytetramethylene carbonate. |
