Abstract: A polyolefin composition which comprises: (a) a polyolefin containing transition metal catalyst residue (excluding metallic co-catalyst residues) at a level below 5 ppm based on the weight of the polyolefin; (b) optionally a first stabilizing component consisting of a phenolic antioxidant or mixture of phenolic antioxidants; (c) optionally a second stabilizing component consisting of a phosphite antioxidant or a mixture of phosphite antioxidants; and (d) a third stabilizing component which acts also as a color suppressant and which is a polyfunctional alcohol, amine or amide or mixtures thereof, with at least one of (b) and (c) present and with the proviso that if the phosphite antioxidant is trilauryl phosphite it must be used in combination with another phosphite. The preferred stabilizing components (b) is 1,3,5-tris(4-tert-butyl-3-hydroxy-2,6 dimethyl,benzyl)-1,3,5-triazine-2,4,6-(1H,3H,5H)-trione or mixed tocopherols.
