摘　　要：以2,4-二羟基二苯甲酮、氯乙酰氯、2,2,6,6-四甲基哌啶胺等为主要原料,经两步亲核取代反应,合成了一种双功能受阻胺光稳定剂。目标产物结构经1H NMR、13C NMR、FT-IR和ESI-HRMS分析进行了确认,并对其进行抗老化性能测试,结果表明其具备良好的防止聚合物光老化的性能。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 twostep 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.
