ABSTRACT:
A method of use of polyaminomethylenephosphonates as dispersing, wetting, and/or stabilizing agents in formulations for cements, detergents, ceramic materials, dyes, synthetic resins, rubbers, drilling fluids, and for reverse osmosis includes the step of adding a polyaminomethylenephosphonate having the formula:wherein n is an integer higher than 2, M is an alkaline metal or the ammonium ion, and R is: —CH2PO3M2; —CH2Z, wherein Z is —CH2OH, —CHOHCH3, —CHOHCH2Cl, or —CHOHCH2OH; —(CH2)mSO3M, m being 3 or 4; —CH2CH2T, wherein T is —CONH2, —CONH2, —CHO, —COOQ, —COOX, CN, wherein Q is —CH3or —C2H5and X is an alkaline metal ion or the ammonium ion; and wherein the polyaminomethylenephosphonate is present in a weight quantity of over 0.01% with respect to the total weight of the formulation.
