Abstract: The invention relates to a process for preparing stabilized compositions based on polyamide. The stabilizer is a phosphorus stabilizer selected from phosphorous acid and hypophosphorous acid. It is introduced before or during the polymerization of the polyamide. The use of these stabilizers prevents foaming phenomena.
