Abstract
Abstract The invention relates to aryl ester-based compounds which have been found to be extremely effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing an amount of an aryl ester-based 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 be incorporated into the organic compositions such as polymers in the polymer melt or dissolved in the polymer dope, or coated on the exterior of the shaped or molded article, film or extruded fiber.
