Abstract

PURPOSE: To obtain a dried cationic polymer useful as a coagulant or the like, by adding a water-soluble inorganic acid to an aqueous solution of a water-soluble polymer having a specified quat. ammonium salt as one of the structural units thereby to precipitate the polymer and dewatering and drying the polymer.
CONSTITUTION: A water-soluble inorganic salt, e.g. NaCl, in an amount sufficient to precipitate the polymer is added to an aqueous solution of a water-soluble polymer having, as one of the structural units, a quat. ammonium salt of the formula, wherein R is H or CH3, R1 and R2 are each a 1W4C alkyl, R3 is benzyl, A is a 1W 4C linear or branched aliphatic group and X is an anionic group which forms a salt with the ammonium nitrogen, e.g., methacryloyloxyethyldimethylbenzylammonium chloride. The precipitated polymer is separated, dehydrated and dried to obtain a dried cationic polymer. This polymer is excellent as a cationic coagulant.
