    摘要: The present invention relates to an UV absorbing polymer composition comprising effective amounts of (a1) a nanoparticulate oxide selected from oxides of the groups 4 and 12 of the periodic table, wherein the oxide is doped with In, Ga and/or Al, and (b1) a UV stabilizing/absorbing substance comprising a sterically hindered amine and/or a polymeric hydroxyphenyl-triazine; or (a2) a nanoparticulate oxide selected from oxides of the groups 4 and 12, and (b2) a UV light stabilizing substance comprising a N-oxygen-substituted sterically hindered amine. Furthermore, the present invention relates to a polymer comprising said composition and the use of said composition as a UV absorber in polymers, particularly in agricultural films or packaging films. Finally, the present invention relates to a process for producing doped nanoparticulate metal oxides.
