OLIGOMER-CONTAINING PHOSPHINATE SCALE INHIBITORS

Calcium carbonate scale is controlled by treating calcium carbonate containing waters with a predominantly phosphinate containing composition where has as its major ingredient more than 32 mole percent of a phosphinicosuccinic acid oligomer having the probable structural formula . M is H, Na, K, NH4...

Zusammenfassung:Calcium carbonate scale is controlled by treating calcium carbonate containing waters with a predominantly phosphinate containing composition where has as its major ingredient more than 32 mole percent of a phosphinicosuccinic acid oligomer having the probable structural formula . M is H, Na, K, NH4, or mixtures thereof; and m and n are either 0 or a small whole number with proviso that either m or n is a small whole number and the sum of m plus n is greater than 2.
