Abstract: The present invention provides acrylic polymer-optical brightener compositions. The invention also provides acrylic polymer-optical brightener compositions further comprising near infrared absorbing compounds. The invention also provides processes for making such compositions. Still further, the invention provides methods for detecting and/or separating fluorescing and/or near infrared emitting articles from non-fluorescing and/or non-near infrared emitting articles.

Abstract: The invention relates to a polymer prepared from the repeat units of residues of a monomer of at least one dicarboxylic acid or ester; a monomer comprising a diol, diamine or a mixture thereof; a monomer comprising at least one sulfonate group and at least one polyester reactive group, and a monomer comprising an optical brightener agent having at least one polyester reactive group. The invention further relates to a method for preparing a polymer. The invention further relates to method of marking an article or composition with the polymer. The invention further relates to a method for detecting and separating an article contacted with the polymer. The invention further relates to an article or composition contacted with the polymer. The invention further relates to a method for enhancing the optical brightness of an article or composition, by contacting the article or composition with the polymer.

Abstract: The invention relates to benzotriazole ortho-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 the benzotriazole ortho-ester 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.
