A series of dendritic compounds containing four hindered amine groups were designed and synthesized from diamines, methyl acrylate and 1,2,2,6,6-pentamethyl-piperidine-4-ol through Michael addition and transesterification. The structures of target compounds were confirmed by 1H NMR and 13C NMR. One of the compounds was chosen to be measured for performances of antioxidation and anti-aging. The results indicated that it exhibited better antioxidation property than Irganox B215, Tinuvin770, Chimassorb944 and Tinuvin622, and better anti-aging property than Tinuvin770.

Key words: dendritic hindered amine light stabilizers, antioxidation, anti-aging, synthesis
