Abstract

PURPOSE: After Hofmann reaction of acrylamide or methacrylamide with a hypohalogenous acid alkali salt, the polymer is separated and directly dried to produce the title powder used as paper reinforcing agent because the aqueous solution is low viscosity and free from precipitation of polymer.
CONSTITUTION: To (A) an aqueous solution of polymer containing at least 50% of acrylamide and metharylamide, are added (B) 0.5W1.0mol, per mole of the carbamoyl group, of a hypohalogenous acid alkali salt or substance capable of forming the same, and (C) 1.4W2.0mol, per mole of component B, of an alkali hydroxide and the mixture is subjected to the Hofmann reaction. An acid is added to the reaction mixture to adjust the pH to less than 5 and the water content in the polymer layer to less than 80wt% (wet base). Then, the polymer is directly dried to remove the water to give the objective polymer powder.
