実験手順

In a 3 L four-necked flask equipped with a stirrer, a reflux condenser tube, a gas introducing pipe, and a thermometer, 500 g of diphenylmethane diisocyanate, 700 g of Actcol P-22 (polyether polyol manufactured by MITSUI TAKEDA CHEMICAL, INC.: weight average molecular weight=1,000), 180 g of TOHO polyethylene glycol #600 (polyethylene glycol manufactured by TOHO Chemical Industry Co., Ltd.: weight average molecular weight=600), and 0.2 g of dibutyltin dilaurate were placed. The mixture was reacted while being stirred at 60° C. for 4 hours. Subsequently, the reactant was stirred while 260 g of 2-hydroxyethyl methacrylate were added dropwise over 2 hours. After the completion of the dropwise addition, the resultant was reacted by stirring for 5 hours to obtain urethane methacrylate. Subsequently, to the urethane methacrylate, 702 g of styrene monomer was added to obtain a urethane methacrylate resin (U-1). The weight average molecular weight of the urethane methacrylate resin (U-1) was 5,315.
