Abstract: The invention relates to a composition, which comprises the components (i) a synthetic polymer; and (ii) a ternary stabilizer combination comprising a benzofuranone, a sterically hindered phenol compound such as a bisphenolic stabilizer and an aliphatic phosphorous (III) compound. A process for manufacturing the aforementioned composition, the use of a stabilizer combination as component (ii) for stabilizing synthetic polymer component (i) against degradation and the use of a stabilizer combination (ii) for stabilizing synthetic polymer (i). As well described are further specific additive mixtures comprising these components and e.g. aminic and/or phenolic and/or chromanol-based antioxidants as further components.

Abstract: The invention relates to a composition, which comprises the components (a) an organic material susceptible to oxidative, thermal or light-induced degradation, which is a polyether polyol, a polyester polyol or a polyurethane; (b) a bisphenolic stabilizer of formula (I) wherein n is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11; and (c) a chromanol stabilizer of formula (II) wherein R1 and R2 are independently of each other H or C1-alkyl. A process for manufacturing the aforementioned composition, the use of an additive mixture comprising component (b) and (c) for stabilizing the component (a) and the additive mixture itself are described.
