ABSTRACT:
N-(2,2,6,6-tetraalkyl-4-piperidinyl)amic acid hydrazides contain a light stabilizing group, a heat stabilizing group and an amic acid hydrazide functionality in the same molecule. The amic acid hydrazide functionality in the compounds enhances the photooxidative stabilizing properties of the hindered amine groups and contributes thermal and oxidative stabilizing and metal complexing properties to the compounds. The novel compounds are excellent light stabilizers for polyolefins, have low volatility and are not readily lost from polymeric systems via volatilization, migration or extraction.
