Processes for Stabilizing Halogen-Free Recycled Thermoplastics, Plastic Compositions, Stabilizer Compositions, and Use of Stabilizer Compositions

摘要

The present invention relates to a process for stabilizing halogen-free regenerated thermoplastics against oxidative degradation, thermal degradation and / or photodegradation. In the process of the present invention, at least one compound capable of reacting with a carbonyl group is combined with at least one primary antioxidant and / or at least one secondary antioxidant, without the use of argitol or cyclitol, and halogen. Introduced into free recycled thermoplastics. The subject of the present invention is a similarly stabilized plastic composition, a stabilizer composition for stabilizing halogen-free regenerated thermoplastics, and their use.
