摘要：Disclosed is a polyolefin polymer stabilising composition, which comprises: (a) a hindered arylalkyl phosphite of the formula (II) (such as 2-butyl-2-ethyl-1,3-propanediol 2,4,6-tri-t-butylphenol phosphite, 2-butyl-2-ethyl-1,3-propanediol 2,4-di-cumylphenol phosphite or 2-butyl-2-ethyl-1,3-propanediol 4-methyl-2,6-di-t-butylphenol phosphite); (b) a trisarylphosphite of the formula (III) (such as tris-(2,4-di-t-butylphenyl) phosphite, tris(4-nonylphenyl phosphite or triphenyl phosphite); and (c) a hindered phenol comprising a molecular fragment selected from the formulae (IVa), (IVb) or (IVc), such as (1,3,5-tris(4-t-butyl-3-hydroxy-2,6-dimethylbenzyl)-1,3,5-triazine-2,4,6-trione).
