Aminovinyl-substituted heterocyclic compounds as stabilizers for organic materials

摘要

The use of an aminovinyl-substituted heterocyclic compound of the general formula I I in which R1 denotes hydrogen, C1-C4-alkyl, C1-C4-alkoxy, or halogen, and, if more than one radical R1 are present, these may be the same or different, R2 denotes cyano or C1-C20-alkoxycarbonyl or C3-C6-cycloalkoxycarbonyl, R3 denotes hydrogen, C1-C18-alkyl, C1-C18-alkoxy, halogen, cyano, C1-C20-alkoxycarbonyl, or C3-C6-cycloalkoxycarbonyl, and, if more than one radical R3 are present, these may be the same or different, X denotes NH, O or S, m is equal to 1 or 2, and n is an integer from 1 to 5, as a stabilizer for organic materials.
