Description

ABSTRACT:
A phenol of the formulae I, II or III ##STR1## in which R.sub.1, R.sub.2 and R.sub.3 are independent of one another and one of these is C.sub.1 -C.sub.12 -alkyl, C.sub.5 -C.sub.6 -cycloalkyl or C.sub.7 -C.sub.9 -aralkyl and the others are hydrogen, C.sub.1 -C.sub.12 -alkyl or C.sub.5 -C.sub.6 -cycloalkyl, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 are independent of one another and one of these is C.sub.1 -C.sub.12 -alkyl or C.sub.5 -C.sub.6 -cycloalkyl and the others are hydrogen, C.sub.1 -C.sub.12 -alkyl or C.sub.5 -C.sub.6 cycloalkyl, or R.sub.4 and R.sub.5, or R.sub.6 and R.sub.7, together with the C atom which links them, form a 5-12-membered ring, R.sub.8, R.sub.9 and R.sub.10 are independent of one another and one of these is C.sub.1 -C.sub.12 -alkyl, C.sub.5 -C.sub.6 -cycloalkyl or C.sub.7 -C.sub.9 -aralkyl and the others are hydrogen, C.sub.1 -C.sub.12 -alkyl or C.sub.5 -C.sub.6 -cycloalkyl, x and y independently of one another are 0, 1, 2 or 3, one of m and n is 1 and the other is 0 or 1, A is a monovalent, divalent or trivalent hydrocarbon radical which, in formula II, can also be interrupted by S, and Z is 1, 2 or 3, corresponding to the valency of A, and, in compounds of the formula II and III, m is 1 and R.sub.4 and R.sub.5 independently of one another are C.sub.1 -C.sub.12 -alkyl or C.sub.5 -C.sub.6 -cycloalkyl and, in compounds of the formula I, R.sub.6 can be bridged with A to form a carbocyclic structure as stabilizers for organic material.
