실험 절차
Into a 300 ml-four-necked flask equipped with a stirrer, a thermometer, and a reflux condenser, a 1 mol/L diallyldimethylamine hydrochloride/diemthylsulfoxide (100 ml) and a 1 mol/L sulfur dioxide/diemthylsulfoxide solution (100 ml) were added and mixed, and azobis-isobutylonitrile (0.82 g) was added as a polymerization initiator to the mixture, followed by polymerizing at 40° C. for 24 hours. The reaction solution was added dropwise to methanol to precipitate the copolymer, filtered through a glass filter, followed by drying under reduced pressure, thereby obtaining 18 g of a copolymerized polymer (Production Example A-4). A weight average molecular weight of the copolymer determined by GPC (Gel Permeation Chromatography) (polyethylene glycol used as a standard) was about 3,000. The repeating unit of this polymer gas the following formula.
