【 摘 要 】

A series of multifunctional hindered amine light stabilizers (HALSs) for monomers were designed and synthesized from cyanuric chloride, allylamine, 2,2,6,6-tetramethylpiperidine-4-ol or 1,2,2,6,6-pentamethylpiperidine-4-ol, and 2-(2-hydroxyphenyl)-1,2,3-benzotriazole derivatives through nucleophilic substitution. The new stabilizers were confirmed by 1 H NMR, 13 C NMR, FT-IR, ESI-HRMS and elemental analysis. The synthesized compounds 5a–f were evaluated for their antioxidant and anti-aging properties. The results indicate that the new HALSs can considerably improve polymer photostability.
