ABSTRACT:
The novel phenol derivatives of the general formula (I) ##STR1## where R is hydrogen, straight-chain or branched C.sub.1 -C.sub.8 -alkyl or cycloalkyl, A is a bridge member and B is a radical of the formula ##STR2## where R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and T.sup.1 independently of one another are each hydrogen, C.sub.1 -C.sub.8 -alkyl, halogen, CN, COOT.sup.2 or CONHT.sup.2, with the proviso that one or more of the radicals R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and T.sup.1 are halogen, CN, COOT.sup.2 and CONHT.sup.2 and T.sup.2 is C.sub.1 -C.sub.8 -alkyl, are useful for stabilizing organic material, in particular polyolefins, to degradation by oxidation.
