The invention relates to multichromophoric compounds which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing a stabilizing amount of the multichromophoric composition to prevent such degradation. These stabilizers are effective in the presence of other additives commonly employed in polymeric compositions including, for example, pigments, colorants, fillers, reinforcing agents and the like. These ultraviolet stabilizers may also be incorporated into the organic compositions in the polymer melt or dissolved in the polymer dope, coated on the exterior of the molded article, film or extruded fiber.
本发明涉及多色团化合物,已发现其是有效的紫外线稳定剂。本发明还涉及含有稳定剂量的多色团化合物的紫外降解有机组成物,以防止这种降解。这些稳定剂在聚合物组成中常用的其他添加剂存在的情况下是有效的,包括例如颜料、染料、填充剂、增强剂等。这些紫外线稳定剂也可以在聚合物熔融中或溶解在聚合物溶液中被纳入有机组成物中,涂覆在成型物、薄膜或挤出纤维的外表面上。
