摘要： This disclosure provides a composition comprising a mixture of molecules of Formula (I): {RO-[CH(CH3)CH2O)]b[CH2-CH2O]a}mP(=O)(O−X+)n(I), wherein R is chosen from linear or branched C10-C18 alkyl or alkenyl groups; a is 0 to 50, b is 0-30, and a+b >0; X+ is potassium, triethanolamine, or H, and m and n are each equal to 1 or 2, such that when m=1 then n=2, and when m=2 then n=1. Moreover, in the mixture some of the molecules have m=1 and n=2 and some of the molecules have m=2 and n=1, wherein the mole ratio of compounds where m=1 to compounds where m=2 is of from 1:1 to 3:1.

摘要： A fluorescent water treatment polymer comprises at least one water soluble carboxylic acid monomer other than maleic acid, at least one sulfonated pyrene-containing fluorescent monomer, and at least one phosphino group wherein the phosphorous atom of the phosphino group is in the polymer backbone. Additional monomers can be present, with the proviso that if maleic acid is present it comprises no greater than 75 mol % of the polymer. Surprisingly, it has been found that when the phosphino group is present the polymers exhibit an unexpectedly strong fluorescent signal strength. The signal strength of the fluorescent monomer in the polymer is further enhanced when the polymer comprises no greater than 75 mol % maleic acid.

摘要： A method of inhibiting scale in an industrial water system includes the steps of dosing the industrial water system with a water treatment polymer comprising at least 10 mol % of carboxylic acid monomer and a quaternized naphthalimide fluorescent monomer as disclosed herein, and then monitoring the fluorescence of the water system. The polymers are also useful for flocculation and coagulation in wastewater treatment.
