Abstract
PURPOSE: To prevent a cationic high polymer of cation formation ratio and the deterioration of the performance as high polymer flocculants, sludge dehydrating agents, etc., by the addition of an acid to an aqueous solution of the cationic high polymer, and by adjusting the pH of the solution to 7 or below.
