| titleOfInvention | Cationic water-soluble polymer, monomer and method for determining the efficiency of a water-soluble polymeric treating agent |
| abstract | A cationic water-soluble polymer comprising from 0.001 to 10 mole percent of a repeating mer unit represented by the formula wherein a is an integer of from 1 to 10. R1 is selected from the group consisting 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 monomer 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-vinyl formamide, dimethylaminoethyl methacrylate methyl chloride quaternary salt, dimethylaminoethyl methacrylate benzyl chloride quaternary salt, methacrylamidopropyl 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. |
