ABSTRACT:
A composition containing a) a polystyrene, substituted polystyrene, copolymer or terpolymer of styrene or of a substituted styrene, polycarbonate, polyester-carbonate, polyurethane, polyamide copolyamide, polyacetyl or polyphenylene oxide and b) at least one compound of the formula I ##STR1## in which R.sub.1 is methyl or ethyl and R.sub.2 is C.sub.2 -C.sub.30 alkyl.
Compounds of the formula I in which R.sub.2 is C.sub.8 -C.sub.30 alkyl are novel and are suitable for stabilizing organic materials against thermal, oxidative and actinic degradation.
