<p>The invention relates to a polyetherester copolymer composition having a strongly improved UV stability, which is eminently suitable for use in film. The polyestherester copolymer composition according to the invention contains 0.1-10 wt.% activated carbon and 0.05-3 wt% of a hindered amine light stabilizer (HALS). Preferably, the contents ar e 0.5-3 and 0.2-1 wt.%, respectively. At a film thickness of 100 .mu.m an increase in the life on the order of a factor 2, relative to th e effect of the sum of the individual components, appears to be possible. Preferably, the molecular weight of the HALS is higher than 1500.< /SDOAB></p> |
