Abstract
The use of an aminovinyl-substituted heterocyclic compound of the general formula I ##STR1## in which R.sup.1 denotes hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, or halogen, and, if more than one radical R.sup.1 are present, these may be the same or different, PA0 R.sup.2 denotes cyano or C.sub.1 -C.sub.20 -alkoxycarbonyl or C.sub.3 -C.sub.6 -cycloalkoxycarbonyl, PA0 R.sup.3 denotes hydrogen, C.sub.1 -C.sub.18 -alkyl, C.sub.1 -C.sub.18 -alkoxy, halogen, cyano, C.sub.1 -C.sub.20 -alkoxycarbonyl, or C.sub.3 -C.sub.6 -cycloalkoxycarbonyl, and, if more than one radical R.sup.3 are present, these may be the same or different, PA0 X denotes NH, O or S, PA0 m is equal to 1 or 2, and PA0 n is an integer from 1 to 5, as a stabilizer for organic materials.
