Abstract
The present invention relates to compositions for water treatment based on biodegradable polymers containing repeating succinyl units, biocidal oxidizing agents and unsubstituted or substituted amidosulphonic acid, their use in, and the process for, conditioning water of cooling circuits.
Claims5
A composition for water treatment comprising:
- a) biodegradable organic polymers having repeating succinyl units,
- b) a biocidal oxidizing agent, and
- c) an unsubstituted or substituted amidosulphonic acid, wherein the unsubstituted or substituted amidosulphonic acid is present in a concentration sufficient to prevent or substantially reduce the reaction between a) and b).
A composition for water treatment comprising:
- a) biodegradable organic polymers having repeating succinyl units
- b) a biocidal oxidizing agent, and
- c) an unsubstituted or substituted amidosulphonic acid, wherein the biodegradable organic polymers contain repeating units selected from the group consisting of the formulae:
- wherein the unsubstituted or substituted amidosulphonic acid is present in a concentration sufficient to prevent substantially reduce the reaction between a) and b).
