実験手順

180 parts of isopropyl alcohol were put in an one-liter four-necked flask equipped with a thermometer, a stirrer, a condenser and a dropping funnel. After nitrogen replacement, the interior temperature of the flask was regulated to about 85° C. Afterwards, a monomer mixture consisting of 180 parts of methyl methacrylate, 15 parts of ethyl methacrylate, 30 parts of n-butyl methacrylate, 30 parts of styrene, 30 parts of N-n-butoxyethyl methacrylate and 15 parts of hydroxyethyl methacrylate were added dropwise into the flask with a catalyst comprising 6 parts of 2,2-azobis(2,4-dimethylvaleronitrile) over about 2 hours. After the completion of the dropwise addition, the reaction was continued at that temperature for further five hours to obtain a colorless, transparent resin solution having a solid content of about 63%.
