  This invention relates to novel UV absorbers, their methods of preparation, their use in stabilizing polymers and polymers so stabilized against the degradative effects of UV light. The novel compounds of formula I are oxamides which are substituted on one or both nitrogens with a 2-hydroxy-3-(2H-benzotriazol-2-yl)benzyl group. The 2-hydroxy-3-(2H-benzotriazol-2-yl)benzyl groups are efficient UV absorbing groups and the oxamide group contributes additional light stabilizing, heat stabilizing and metal complexing properties to the compounds. The compounds have low-volatility and are especially useful as UV stabilizers for engineering resins processed at high temperatures.

  这项发明涉及新型紫外线吸收剂，其制备方法，其在稳定聚合物中的使用以及通过紫外线光的降解作用而得到稳定的聚合物。公式I的新型化合物是氧酰胺，其在一个或两个氮上被2-羟基-3-(2H-苯并三唑-2-基)苯甲基基团取代。2-羟基-3-(2H-苯并三唑-2-基)苯甲基基团是高效的紫外线吸收基团，而氧酰胺基团则为化合物提供了额外的光稳定、热稳定和金属络合性能。这些化合物具有低挥发性，特别适用于在高温下加工的工程树脂的紫外线稳定剂。
