  Process for preparing reactive hindered amine light stabilizers

  摘要：

  含有光稳定基团、热稳定基团和反应性肼基官能团的二羧酸N-(2,2,6,6-四烷基-4-哌啶基)酰肼类化合物位于同一分子中。这些反应性稳定剂通过将4-氨基-2,2,6,6-四烷基哌啶与二羧酸二酯（或单酯酸氯化物）或二烯酸二烷基酯反应，然后通过中间体单酯酰胺的酯基水解反应制备而成。这些化合物可用于向共聚物或共反应聚合物引入永久的热和光稳定性。当仅与寻求稳定的聚合物混合而不是反应时，它们也可用于稳定惰性聚合物体系，以抵御热和光的降解作用。

  N-(2,2,6,6-tetraalkyl-4-piperidinyl)amide-hydrazides of dicarboxylic acids contain 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 or dialkyl itaconates followed by hydrazinolysis of the ester group of the intermediate mono esteramide. 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.
