Compounds containing both a UV-absorbing moiety and a 1-hydrocarbyloxy hindered amine moiety are effective stabilizers for protecting polymer compositons against the deleterious effects of actinic light. The UV-absorbing moieties include the substituted 2H-benzotriazoles, s-triazines, acrylates, benzophenones, oxanilides and oxamides.
同时含有紫外线吸收分子和 1-hydrocarbyloxy 受阻胺分子的化合物是有效的稳定剂,可保护聚合物复合物免受放 射光的有害影响。紫外线吸收分子包括取代的 2H-苯并三唑、s-三嗪、
丙烯酸酯、
二苯甲酮、
草酰苯胺和草酰胺。
