Polymeric compounds containing piperidine radicals and their use as stabilizers for synthetic polymers

摘要

Novel light stabilizers, heat stabilizers and oxidation stabilizers for synthetic polymers have been synthesized; these are of the formula: <IMAGE> (I) in which R3 and R5 can be identical or different and are radicals of formula (III), (IV), (V), (VI) <IMAGE> <IMAGE> <IMAGE> and R5 additionally can be a radical of formula VII <IMAGE> (VII) and R4 is C2-C18-diacyl or a radical of the formula <IMAGE> (VIII)
