摘要： The precipitation and deposition of alkaline-earth metal scales in an aqueous system is inhibited by comprising adding to the system an anionic polyelectrolyte and an anionic surfactant, the weight ratio of polyelectrolyte to surfactant being in the range from 1000:1 to 1:10. Compositions containing the electrolyte and surfactant in that ratio are novel.

in which each R. which may be the same as or different from the other, is hydrogen, phenyl, C 1-3 alkyl or -COOX. R' is a straight or branched chain of from 0 to 12 carbon atoms, and X is hydrogen or an alkali or alkaline-earth metal; 1.5 to 85 weight % of a monomer of formula:
where each R 6 , which may be the same as or different from the other, is hydrogen, phenyl or C 1-3 alkyl, preferably hydrogen, methyl, or ethyl, and each R 2 , which may be the same as or different from the other, is hydrogen or C 1-3 alkyl; and 0.5 to 40 weight weight % of a cationic-containing monomer containing quaternary ammonium, phosphonium or sulfonium ion.
