Patent ID: 7659315

Claim:
A method for increasing dispersion in a liquid solution or dispersion, the method comprising: adding a polyaminomethylenephosphonate composition to the liquid solution or dispersion, the polyaminomethylenephosphonate composition having the formula wherein n is an integer higher than 2, wherein M is a cation selected from the group consisting of the alkaline metal ions and the ammonium ion, wherein each of the R groups is independently selected from the group consisting of, —CH 2 PO 3 M 2 , —CH 2 Z, wherein Z is selected from the group consisting of —CH 2 OH, —CHOHCH 3 , —CHOHCH 2 Cl, —CHOHCH 2 OH, —(CH 2 ) m SO 3 M, wherein m is 3 or 4, —CH 2 CH 2 T, wherein T is selected from the group consisting of —CONH 2 , —CHO, —COOQ, —COOX, —CN, wherein Q is —CH 3 or —C 2 H 5 ,and wherein X is a cation selected from the group consisting of the alkaline metal ions and the ammonium ion, wherein the polyaminomethylenephosphonate composition is added in a weight quantity higher than 0.01% of total solution or dispersion weight, and wherein the liquid solution or dispersion further comprises a ceramic composition selected from the group consisting of clay, ceramic glass, and silicone carbide whiskers.
