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.
