Description

ABSTRACT:
Novel polymeric compounds of the repeating structural unit (I) ##STR1## in which R.sub.1 is hydrogen, 0.degree., CN, cyanomethyl, C.sub.1 -C.sub.12 -alkyl, C.sub.3 -C.sub.12 -alkenyl or C.sub.3 -C.sub.12 -alkynyl subject to the proviso that the carbon atom attached to the nitrogen atom is a primary carbon atom, C.sub.7 -C.sub.12 -aralkyl, C.sub.1 -C.sub.12 -acyl, 2,3-epoxypropyl or C.sub.2 -C.sub.6 -alkyl substituted by OH, R.sub.2 is C.sub.2 -C.sub.18 -alkylene, C.sub.4 -C.sub.18 -alkylene substituted by 1 or 2 oxygen or nitrogen atoms in the chain, C.sub.5 -C.sub.18 -cycloalkylene, C.sub.6 -C.sub.18 -arylene or C.sub.8 -C.sub.18 -aralkylene, R.sub.3 is as defined for R.sub.2 or is a group of the formula (II) or (III) ##STR2## in which R.sub.4 is hydrogen or C.sub.1 -C.sub.4 -alkyl and R.sub.5 is C.sub.2 -C.sub.12 -alkylene, C.sub.4 -C.sub.12 -alkenylene subject to the proviso that the carbon atom attached to the nitrogen atom is a primary carbon atom, or is C.sub.8 -C.sub.12 -aralkylene are useful as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials.
