Abstract A series of novel hindered amine light stabilizers (HALSs) containing four hindered amine groups were designed and synthesized from diamines, methyl acrylate, and 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. Two of them were chosen to be evaluated for their antioxidation and anti-aging
