Abstract:
    A molding material comprising the following components: (a) 100 pts.mass of a polyamide and (b) 0.005 to 10 pts.mass of a compound having at least two carbonate units, for simultaneously extruding with a molding material based on a highly melting polymer having a crystallite melting point Tm of at least 255[deg.]C and/or a glass transition temperature Tg of at least 180[deg.]C. A multilayer composite material having a good quality, especially good layer distribution and wall thickness distribution is obtained.
