Abstract: Described herein are polyhydric alcohols having more than two hydroxyl groups in polyamide compositions including at least one polyamide to increase the weld seam strength after thermal aging of shaped articles produced from the polyamide composition by injection molding. During the injection molding, at least two flow fronts of the polyamide composition collide and form at least one weld seam.
