Abstract
New N-substituted piperidines useful as light stabilizers in synthetic resins are disclosed. They are 1-(2,7-octadienyl)-2,2,6,6-tetraalkylpiperidines wherein the alkyl groups are independently selected lower alkyl groups such as methyl or ethyl and the 3 and 5 positions may be substituted by methyls. The ring may be monounsaturated; a new compound 1-(2,7-octadienyl)-2, 2,6,6-tetramethyl-3-pyridine is described.
