Patent ID: 8173728

Claim:
A stabilized polymer composition comprising a) a non halogen containing thermoplastic polymer; b) an aliphatic tertiary amine with a molecular weight greater than 400 g/mol, which is not a 2,2,6,6 tetramethylpiperidine derivative; and c1) a UV-absorber selected from the group consisting of hydroxyphenyl benzotriazoles, hydroxyphenyl triazines, hydroxy benzophenones and oxalic anilides; or c2) a light stabilizer selected from sterically hindered amines; or c3) a mixture of the UV-absorber, component c1) and the sterically hindered amine, component c2) and wherein the tertiary amine is a compound of formula (a), (b), (c), (d), (e), (f), (g), (h), (i) or (j) wherein R 301 , R 302 and R 303 are independently C 10 -C 36 alkyl; R 304 , R 305 and R 306 are independently C 9 -C 36 alkyl; R 310 and R 311 are independently hydrogen or C 1 -C 18 alkyl; R 307 and R 308 are independently C 1 -C 8 alkylene; n is a number from 2 to 20; m is a number from 4 to 20; and x, y independently are numbers from 3 to 20.
