Abstract

PURPOSE: To obtain the titled modified product useful as a paper additive such as a paper-strengthening agent, freeness improver or flocculant, by reacting an acrylamide polymer with a hydroxyl group-containing quat. pyridinium salt, etc., and a hypohalite.
CONSTITUTION: A cation-modified polyacrylamide is produced by reacting an acrylamide polymer with a compound of the formula, wherein A is a 2W5C saturated bivalent group, R1 and R2 are each H or a 1W4C alkyl and X is a negative group capable of forming a salt together with the aminic nitrogen (e.g., N-hydroxyethylpyridinium chloride or butyl-N-hydroxyethylpyridinium chloride) and a hypohalite (e.g., sodium hypochlorite) or a substance capable of forming a hypohalite, in the presence or absence of an alkali. The modified product can be used effectively as a paper additive such as a paper strengthening agent, freeness improver, filler retention aid, size fixation aid or flocculant.
