Polymers containing optical brightener compounds copolymerized therein and methods of making and using therefor |
摘要 |
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.
