Abstract: 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; R 1 is, hydrogen or lower alkyl of 1 to 4 carbons; R 2 is, e.g., hydrogen or alkyl of 1 to 20 carbons; R 3 is, e.g., a direct bond or an alkylene or branched alkylene diradical of 1 to 14 carbons; and R 4 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.

Abstract: N-(2,2,6,6-tetraalkyl-4-piperidinyl)amine-hydrazides of dicarboxylic acids contain a light stabilizing group, a heat stabilizing group, a 5-membered lactam ring and a reactive hydrazide functionality in the same molecule. The reactive stabilizers can be prepared by reacting 4-amino-2,2,6,6-tetraalkylpiperidines with dialkyl itaconates 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. They are also useful in the stabilization of inert polymeric systems against the degradative effects of heat and light when merely mixed with, rather than reacted with, the polymers for which stabilization is sought.
