ABSTRACT:
The present invention provides a method for treating aqueous systems to reduce or prevent the deposition of barium sulphate and other insoluble sulphates therein, comprising the addition to the water of an effective amount of an interpolymer of an ethylenically polymerizable carboxylic acid, and at least one of an ethylenically polymerizable dicarboxylic acid or other copolymerizable comonomer. The polymers are particularly effective in preventing scale precipitate at high levels of barium (e.g. 700 ppm) and under low pH conditions.
