Title:
METHOD FOR PRODUCING DIALLYLDIALKYLAMMONIUM SALT/MALEIC ACID COPOLYMER
Document Type and Number:
Japanese Patent JP2010248460
Kind Code:
A
Abstract:

To provide a method for producing a copolymer of a diallyldialkylammonium salt and maleic acid, in which a monomer and an initiator for polymerization hardly remain, as a result, which can stably demonstrate a performance which is excellent in various applications.

The method for producing a copolymer of a diallyldialkylammonium salt and maleic acid comprises: 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 produce a copolymer comprising a diallyldialkylammonium salt constituting unit and a maleic acid constituting unit.
