A stabilized polyethylene composition which comprises (a) polyethylene, and (b) an effective light stabilizing amount of (A) one or more compounds containing a group of formula I [Figure] (I) in which R is hydrogen, C1-C4-alkyl, allyl, benzyl, acetyl, acryloyl, 2-hydroxyethyl or 2-hydroxypropyl, and
A stabilized polyethylene composition which comprises (a) polyethylene, and (b) an effective light stabilizing amount of (A) one or more compounds containing a group of formula I [Figure] (I) in which R is hydrogen, C1-C4-alkyl, allyl, benzyl, acetyl, acryloyl, 2-hydroxyethyl or 2-hydroxypropyl, and (B) one or more than one oxide or hydroxide of Al, Mg or Zn; wherein the compound of component (A) is selected from the group consisting of the compounds of the formulae (II), (III), (IV), (X) and (XXI). [Figure] (II) in which R1 is C1-C8-alkyl, cyclohexyl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, R2 is hydrogen or C1-C8-alkyl, R3 is hydrogen or methyl, R4 is C2-C6-alkylene and n is a number from 2 to 20; [Figure] (III) in which R1 is hydrogen or methyl, R2 is C2-C6-alkylene, R3 is C2-C6-alkylene, 2-hydroxytrimethylene or xylylene and n is a number from 2 to 20. [Figure] (IV) in which R1 is hydrogen or methyl, R2 is hydrogen, C1-C8-alkyl, cyclohexyl, 2,2,6,6-tetramethyl-4-piperidyl or 1,2,2,6,6-pentamethyl-4-piperidyl, n is 2, 3 or 4 and R3 is the radical of an n-valent polyamine; [Figure] (X) [Figure] in which R1 is hydrogen or methyl, R2 is C2-C6-alkylene and n is a number from 2 to 20; and [Figure] (XXI) in which R1 is C1-C8-alkyl, cyclohexyl, benzyl or C2-C4-alkyl substituted by C1-C4-alkoxy or dimethylamino or diethylamino, R2 is hydrogen or methyl, X is morpholino or a group －NR3R4, －OR5 or a group [Figure] where R3 and R4 which can be identical or different are C1-C8-alkyl, cyclohexyl, benzyl or C2-C4-alkyl substituted of OH, C1-C4-alkoxy, dimethylamino or diethylamino, R4 can also be hydrogen and R5 is C1-C8-alkyl, allyl, cyclohexyl or benzyl.
