실험 절차

In a flask equipped with a stirrer, a thermometer and a reflux condenser, 222 parts of isophorone diisocyanate was charged. After heating to 70° C. while stirring, 116 parts of hydroxyethyl acrylate was added dropwise over one hour and reacted to obtain an intermediate. Then, in a flask equipped with a stirrer, a thermometer and a reflux condenser, 144 parts of acrylic acid was added to 376 parts of a bisphenol A epoxy resin (epoxy equivalent: 118 g/eq) and the reaction was conducted at 100° C. for 8 hours. To the reaction product, 338 parts of the above intermediate was added and the reaction was conducted at 80° C. for 5 hours to obtain a urethane acrylate (H-2) as a radical polymerizable oligomer (A1).
