Abstract:
The invention relates to stabilized thermoplastic polymers, in particular polyolefin films. The stabilizing composition contains a tertiary amine with a molecular weight greater than 400 g/mol, a UV-absorber and/or a sterically hindered amine light stabilizer (HALS). Further aspects of the invention are a process for stabilizing thermoplastic polymers and the use of the above composition for stabilizing thermoplastic polymers.
