Abstract (en)
[origin: WO02053633A2] The invention concerns a method for making stabilised polyamide compositions. The stabilizer is a phosphorous stabilizer selected among phosphorous acid and hyperphosphorous acid. It is introduced before or during polymerisation of the polyamide. The use of said stabilizers enables to avoid foaming phenomena.
