Abstract (en)
[origin: WO2020083740A1] The present invention relates to a method of stabilizing virgin thermoplastic material against oxidative, thermal and/or actinic degradation. In the method of the invention, at least one polyphenol and at least one alditol and/or cyclitol are introduced into a virgin thermoplastic material. The method of the invention can stabilize virgin thermoplastic material with high efficacy and in a very environmentally friendly and inexpensive manner against oxidative, thermal and/or actinic degradation. The present invention additionally also relates to correspondingly stabilized virgin thermoplastic material and to moulding compounds and mouldings produced therefrom. The present invention also further relates to stabilizer compositions and to the use thereof for stabilization of virgin thermoplastic material against oxidative, thermal and/or actinic degradation.
