| Abstract: | A study was made of the low-temperature hydrolysis of high-moleculer-weight polyacrylamide Praestol under the action of NaOH in dilute aqueous solution. The performance of the hydrolyzed and nonhydrolyzed polymer when combined with aluminum sulfate in treatment of natural water was estimated. |
