    Abstract: The use of moulding materials (I) containing (a) 100 parts by weight (pts. wt.) polyamide and (b) 0.005-10 pts. wt. of a compound (II) with at least two carbonate units, for coextrusion with a moulding material (III) based on a high-melting polymer with a crystallite melting point (Tm) of at least 255 deg C and/or a glass transition point(Tg)of at least 180 deg C. Independent claims are included for (1) a method for the production of multilayer composites by making a polyamide moulding material, mixing this with 0.005-10 pts. wt. (II) per 100 pts. wt. polyamide, optionally storing and/or transporting the mixture and then coextruding it with (III) (2) multilayer composites obtained by this method .

    Abstract: Preparation of molded articles under condensation of a polyamide molded mass (A), where the polyamide portion contains at least 5 ppm of phosphorus in the form of acid compound, with a compound (I) having at least two carbonate units, comprises adding 0.001-10 wt.% of a salt of a weak acid to (A) before/during compounding, preparing a mixture of finished compounds and (I), transporting the mixture, which is optionally stored, and processing the mixture to molded articles, where the condensation is carried out first. An independent claim is included for a molded mass obtained by the process.
