METHOD FOR PRODUCING DIALLYLDIALKYLAMMONIUM SALT/MALEIC ACID COPOLYMER

摘要

Disclosed is a process for producing a copolymer of a diallyldialkylammonium salt and maleic acid, characterized by comprising: subjecting a monomer mixture, which contains the diallyldialkylammonium salt and maleic acid, to polymerization in water or a polar solvent in the presence of a persulfate employed as a radical-polymerization initiator; and, after the completion of the polymerization, decomposing the radical-polymerization initiator to thereby give a copolymer comprising a diallyldialkylammonium salt constituting unit and a maleic acid constituting unit.
