反応手順
In a flask equipped with a stirring blade, 348 parts (2 mol) of TDI (2,4-tolylene diisocyanate) was charged and 2000 parts (1 mol) of polytetramethylene glycol (number-average molecular weight of 2000) and dibutyltin diacetate were added while stirring. After heating to 70° C. while paying attention to heat generation, 0.2 parts of p-methoxyphenol and 1 part of 2,6-tertiary butyl-4-methylphenol were added. The reaction was conducted at the same temperature for 7 hours. Then, 232 parts (2 mol) of HEA (2-hydroxyethyl acrylate) was charged and the reaction was further reacted 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 (OS-2) as a radical polymerizable oligomer (A1).
