Compounds containing both a UV-absorbing moiety and a 1-hydrocarbyloxy hindered amine moiety are effective stabilizers for protecting polymer compositions 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UV吸收基团和1-羟基烷氧基受阻胺基团的化合物是有效的稳定剂,用于保护聚合物组合物免受光化学光的有害影响。UV吸收基团包括取代的2H-苯并三唑、s-三嗪、丙烯酸酯、苯甲酮、氧代苯酰胺和氧代酰胺。
