Polyalkyldiazaspirodecanyl-acetic-acid derivatives, process for their preparation and their use as light protecting agents for organic polymers

摘要

New polyalkyldiazaspirodecanylacetic acid derivatives are prepared by reacting diazaspirodecanes of the formula IMAGE in which X is IMAGE with halogenoacetic acid derivatives, and, if desired, reacting products thus obtained further with alcohols or amines. The compounds can be used as light stabilizers for plastics and lacquers.
