  • Polychromophoric dibenzoxazole ultraviolet stabilizers and their use in organic compositions
    Patent number: 4174321
    Abstract: The invention relates to polychromophoric dibenzoxazole 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 polychromophoric dibenzoxazole 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.
