  Hindered amines based on various 2,2,6,6-tetralkylated nitrogen-containing heterocyclic moieties wherein the hindered nitrogen atom on the ring is substituted with OR₁ substituents and the 4-position of the ring is substituted with OR₂ substituents are effective in protecting a variety ofpolymeric substrates against the adverse effects of light, heat and oxygen.

  基于各种 2,2,6,6-四烷基化含氮杂环分子的受阻胺，其中环上的受阻氮原子被 OR₁ 取代基取代，环的 4 位被 OR₂ 取代基取代，可有效保护各种聚合物基材免受光、热和氧的不利影响。
