  There are provided reactive hindered amine light stabilizers of the formula wherein R is e.g., hydrogen, hydroxyl or alkyl of 1 to 20 carbons; R1 is, hydrogen or lower alkyl of 1 to 4 carbons; R2 is, e.g., hydrogen or alkyl of 1 to 20 carbons; R3 is, e.g., a direct bond or an alkylene or branched alkylene diradical of 1 to 14 carbons; and R4 is, e.g., hydrogen or a primary or secondary alkyl group of 1 to 8 carbons, containing a light stabilizing group, a heat stabilizing group, and a reactive hydrazide functionality in the same molecule. The reactive stabilizers are prepared by reacting 4-amino-2,2,6,6-tetraalkylpiperidines with diesters (or mono ester acid chlorides) of dicarboxylic acids followed by hydrazinolysis of the ester group of the intermediate mono ester-amide. The compounds are useful for introducing permanent heat and light stability to coreactive polymers or copolymers.
