Abstract

PURPOSE: To stabilize a Mannich reaction product of polyacrylamide in an acidic state, by adding at least a specified amount of an alkylating agent thereto.
CONSTITUTION: To a Mannich reaction product of polyacrylamide is added an alkylating agent in an amount at least equimolar to the total of undissociated amines and free formaldehyde contained in the product to adjust the pH of the product to below about 3.0. Said undissociated amines do not mean the total amount of the amines used in the Mannich reaction of polyacrylamide. For example, when an acid is added to the above product, neutralization proceeds stepwise and, after completion of the dissociation of unreacted amines, polymer-bound amines are dissociated, because unreacted dialkylamines can be dissociated more easily than the polymer-bound amines.
