Reaction Conditions

Reaction Steps

Thereafter, a mixture of 10.39 parts by mass of acrylic acid and 111.76 parts by mass of methacrylic acid, and a solution of 14.44 parts by mass of 2,2′-azobis[2-(2-imidazolin-2-yl)propane] and 11.32 parts by mass of concentrated sulfuric acid dissolved in 80.00 parts by mass of deionized water, were simultaneously poured into the flask over 60 minutes. The mixture was kept warm at 85° C. for 2 hours to complete the polymerization reaction, and then the resultant was cooled and taken out. Thus, an acrylic acid/methacrylic acid copolymer was obtained. The non-volatile component fraction was measured, and it was 40% by mass.
