ABSTRACT:
The invention relates to piperidinyl hydrogen 2-hydroxyalkyl phosphates which have been found to be effective ultraviolet stabilizers. The invention also relates to piperidinyl hydrogen 2-hydroxyalkyl phosphate salts which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing a stabilizing amount of the piperidinyl hydrogen 2-hydroxyalkyl phosphates or salts thereof 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, or coated on the exterior of the molded article, film or extruded fiber.
