Abstract: There are provided hindered amine light stabilizers of the general formula
wherein the hindered amine is attached to the nitrogen of an imide which also is attached to an aromatic group which contains a carboxy group and wherein
R 1 is, e.g., hydrogen or substituted or unsubstituted aliphatic of 1-20 carbons; Xis
R 2 is, e.g., oxyl, hydroxy or substituted or unsubstituted aliphatic acyl of 1-20 carbons; R 3 is e.g., hydrogen or substituted or unsubstituted aliphatic of 1-20 carbons; A is, e.g., halogen or sulfate; and R 4 is, e.g., hydroxy, halogen or a substituted or unsubstituted, mono or polyfunctional alcohol, amine, mercaptan or molecular mixture thereof, the carboxy group being a site for preparing unique derivatives, both polymeric and non-polymeric, useful as additives for preventing degradation of polymers and copolymers.
