A water soluble isopropenylphosphonic acid copolymer composition and method of use thereof are disclosed. The copolymer comprises repeat units (a) of the formula ##STR1## wherein X=OH or OM, wherein M is a cation; and repeat units (b) of the formula ##STR2## wherein R.sub.1 is chosen from the group consisting of hydroxy, hydroxylated alkoxy, and amide and water soluble salts thereof; R.sub.2 is H, or lower alkyl of from 1-3 carbon atoms. These copolymers are effective in inhibiting the precipitation of certain scale forming salts, and also act to inhibit corrosion in water systems.
本发明公开了一种水溶性异丙基磷酸酯共聚物组合物及其使用方法。该共聚物包括重复单元(a)的公式##STR1##其中X = OH或OM,其中M是阳离子;和重复单元(b)的公式##STR2##其中R.sub.1选择自羟基,羟基化的烷氧基和酰胺及其水溶性盐;R.sub.2为H或1-3个碳原子的低碳烷基。这些共聚物在抑制某些产生沉垢的盐的沉淀方面是有效的,并且还能够在水系统中抑制腐蚀。
