| 摘要 |
The invention relates to the use of polynuclear phenolic compounds with up to 20 bezene nuclei per molecule, obtained by reaction of a tetrahydrobenzoxazine I, where R = a hydrocarbon group and R, R, Rand R independently = H, OH, or hydrocarbon groups, with one or more of the same or different phenols II, where R, R, R and R independently = H, OH or hydrocarbon groups and/or with one or more of the same or different tetrahydrobenzoxazines I, with the proviso that at least one of the substituents has 13 to 3,000 carbon atoms and the remaining substituents, when hydrocarbon groups, have 1 to 20 carbon atoms, as stabilisers for stabilising inanimate organic materials against the effects of light, acid and heat. |
