実験手順
A mixture of 43 parts by mass of the polymer (white solid) obtained through the production of an intermediate, 20 parts by mass of n-octadecylamine, 1 part by mass of pyridine, and 420 parts by mass of toluene is stirred at a temperature of 100° C. for 3 hours. After the mixture is cooled, the reaction solution is added to 8000 parts by mass of methanol in 15 minutes while stirring and is further stirred for 1 hour. The precipitated solid is filtered and is dried under depressurization, whereby 43 parts by mass of light yellowish white solid (specific copolymer) is obtained. The molecular weight measured through the use of a high-speed liquid chromatography method is 14,000. As the result of neutralization titration using a potassium hydroxide ethanol solution, the ratio of the semi-maleic acid amide component and the maleinimide component is 6:4.
