  • Radiation curable compositions containing 5-halo-6-halomethyluracil derivatives as photoinitiators
    Patent number: 4189366
    Abstract: Ethylenically unsaturated compositions such as acrylic and methacrylic acid esters, vinyl esters, vinyl halides, unsaturated amides such as acrylamide, vinyl aromatics such as styrene, and various aliphatic and aromatic polyesters containing any of the above or other modifying components such as maleic, fumaric, itaconic, citraconic and the like, are very effectively and rapidly cured with certain 5-halo-6-halomethyluracil photoinitiators. These curable systems have extensive utility in the surface coatings industry, particularly in regard to cured protective coatings.

  • Bichromophoric benzoxazole ultraviolet stabilizers
    Patent number: 4169837
    Abstract: The invention relates to bichromophoric heterocyclic ester compounds which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing a stabilizing amount of these bichromophoric heterocyclic ester compositions 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.
    Type: Grant
