Procedure

Into a sealed glass tube were introduced 26 g of N-n-octylmaleimide, 4.8 g of maleic anhydride, and 0.04 g of dimethyl-2,2′-azobisisobutyrate as a polymerization initiator. After nitrogen displacement, a radical polymerization reaction was conducted under the conditions of a polymerization temperature of 60° C. and a polymerization time of 5 hours. Chloroform was added after the reaction to obtain a polymer solution. Thereafter, this solution was mixed with excess methanol to thereby precipitate the polymer. The polymer obtained was taken out by filtration, subsequently sufficiently washed with methanol, and dried at 80° C. Thus, an N-n-octylmaleimide-maleic anhydride copolymer resin was obtained in an amount of 18 g. The N-n-octylmaleimide-maleic anhydride copolymer resin obtained contained maleic anhydride residue unit in an amount of 20% by weight and had a number-average molecular weight of 140,000.
