Use of polyaminomethylenephosphonates as dispersing agents

232223222m322223 25 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: -CHPOM; -CHZ, wherein Z is -CHOH, -CHOHCH, -CHOHCHCl, or -CHOHCHOH; -(CH)SOM, m being 3 or 4; -CHCHT, wherein T is -CONH, -CONH, -CHO, -COOQ, -COOX, CN, wherein Q is -CHor -CHand 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.
