실험 절차

In a flask equipped with a stirring blade, 260 parts (2 mol) of 2-hydroxypropyl acrylate(molecular weight of 130) was charged and 174 parts (1 mol) of TDI (2,4-tolylene diisocyanate) was added dropwise. After heating to 70° C. while paying attention to heat generation, the reaction was conducted at the same temperature for 7 hours. After confirming the disappearance of absorption of NCO by infrared absorption spectrum, the reaction product was taken out to obtain a urethane acrylate (H-1) as a radical polymerizable oligomer (A1).
