ABSTRACT:
The invention relates to piperidinyl hydrogen alkylene or arylene phosphates which have been found to be effective ultraviolet stabilizers. The invention also relates to piperidinyl hydrogen alkylene or arylene phosphate salts which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable or organic compositions containing a stabilizing amount of the piperidinyl hydrogen alkylene or arylene 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.
