Claim:
An ethylene homo- or copolymer composition comprising: (i) at least two sterically hindered amine compounds in an amount of from 100 to 10,000 ppm, calculated on total weight of the stabilized polymer composition; (ii) a stabilizer selected from the group consisting of: tetrakis-(methylene-(3,5-di-tert-butyl-4-hydrocinnamate))methane, octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)-propionate, 4-((4,6-bis(octylthio)-1,3,5-triazin-2-yl)amino)-2,6-di-tert-butylphenol, N,N′-hexane-1,6-diylbis(3-(3,5-di-tert-butyl-4-hydroxyphenylpropionamide)), and 5,7-di-t-butyl-3-(3,4-dimethylphenyl)-3H-benzofuran-2-one; and (iii) an organic phosphite selected from the group consisting of: 2,4-bis(1,1-dimethylethyl)phenol phosphite and phosphorous acid, P,P′-[1,1′-biphenyl]-4,4′-diyl P,P,P′,P′-tetrakis(2,4-bis(1,1-dimethylethyl)phenyl]ester).
