반응 단계
400 parts by weight of polycaprolactone diol having an average molecular weight of 800, 131 parts by weight of 2-hydroxypropyl acrylate, 0.5 part by weight of dibutyltin dilaurate as a catalyst and 1.0 part by weight of hydroquinone monomethyl ether as a polymerization inhibitor were mixed while heating them to 50° C. with stirring. Then, 222 parts by weight of isophorone diisocyanate was dropwise added, and further the temperature was raised to 80° C. with stirring to carry out urethanation reaction. Making sure that the NCO conversion reached 99% or more, the reaction temperature was dropped to obtain urethane acrylate B.
