发明名称 FLUORESCENT CATIONIC MONOMERS USEFUL FOR TAGGING WATER SOLUBLE POLYMERS
摘要 A cationic water-soluble polymer comprising from 0.001 to 10 mole percent of a repeating mer unit represented by the formula (see fig. I) OR (see fig. II) wherein a is an integer of from 1 to 10. R1 is selected from the group consistin g of hydrogen and methyl groups. R2 and R3 are methyl groups. fluor is a fluorescing moiety and X is selected from the group consisting of chloride. iodide and bromide ions and wherein the polymer also contains from 90 to 99.999 mole percent of a remaining portion of randomly distributed vinylic mer units selected from at least one of the mono mer groups consisting of acrylamide, acrylic acid, methacrylamide, vinyl acetate, dimethylaminoethyl acrylate methyl chloride quaternary salt, dimethylaminoethyl acrylate benzyl chloride quaternary salt. diallyldimethyl ammonium chloride, N-v inyl formamide, dimethylaminoethyl methacrylate methyl chloride quaternary salt, dimethylaminoethyl methacrylate benzyl chloride quaternary salt, methacrylamidop ropyl trimethyl ammonium chloride and acrylamidopropyl trimethyl ammonium chloride. Preferably, fluor is selected from the group consisting of 1-(substituted)naphthalene, 9-(substituted)anthracene, 2-(substituted)quinoline monohydrochloride, 2-(substituted)benzimidazole, 5-(substituted)fluorescein, 4-(substituted)coumarin and 3-(substituted)-6,7-dimethoxy-1-methyl-2(1H)-quinoxazolinone. Most preferably, fluor is a coumarin derivative. Monomers of the structures described above are also disclosed. Moreover, a method for determining the efficiency of water-soluble polymeric treating agents utilizing the above-mentioned polymers is also disclosed.
