Abstract

A bifunctional hindered amine light stabilizer (HALS) was designed and synthesized from 2,4-dihydroxybenzophenone, chloroacetyl chloride and 2,2,6,6-tetramethylpiperidine-4-amine through two-step nucleophilic substitutions. The structure of the target compound was confirmed by ¹H NMR, ¹³C NMR, FT-IR and ESI-HRMS. Its anti-oxidant and anti-aging properties were evaluated. The obtained results indicate that this synthesized stabilizer is efficient for inhibiting degradation of polymer materials with good oxidation resistance and photo-stabilization.
