摘要：

The instant invention relates to synergistic stabilizer compositions for thermoplastic polymers comprising a) a random copolymer of ethylene (I) and hindered amine moieties containing acrylates/ methacrylates (II) <CHEM> and b) at least one light stabilizing compound based on sterically hindered amines (HAS) and/or UV absorbers. Polyethylene based articles which are exposed to permanent extraction and agressive and/or hazardous chemicals show significantly improved lifetime as measured by carbonyl formation or time to brittleness.
