ABSTRACT Mindered amine light stabilizers are provided in which the hindered amine is attached to the nitrogen of an imide which also is attached to an aromatic group which contains a carboxy group which is a site for preparing unique derivatives, both polymeric and non-polymeric, useful as additives for preventing degradation of polymers and copolymers. The compounds have the structure: Image wherein R1 is selected from hydrogen and substituted or unsubstituted aliphatic, aryl or araliphatic; x is a substituted or unsubstituted secondary amino group; s is an integer of 1 to 100: and R4 is selected from hydroxy, -0.theta., halogen or the residue from a substituted or unsubstituted, mono or polyfunctional alcohol, amine, mercaptan or molecular mixture thereof, including hydroxy and amine-containing polymers which may be in the backbone, pendant and terminally functionalized.
