ABSTRACT:
This invention is directed to the method of dispersing inorganic matter and to scale inhibition in an aqueous system by addition thereto of an effective amount to obtain synergistic threshold inhibition of a phosphonocarboxylic acid and a polymeric phosphinocarboxylic acid, the phosphonocarboxylic acid being a phosphonoalkane carboxylic acid containing preferably two phosphono groups, 2 to 4 carbon atoms in the alkane hydrocarbon group, and three carboxylic acid groups; and the polymeric phosphinocarboxylic acid contains features of both phosphonates and polyacrylates.
