반응 단계
Under a flow of nitrogen, 200 g of hydroxy polyester (Uralac ZW 3896 P) were dissolved in 300 g of toluene at 100° C. Then, 39.5 g hydroxyethylacrylate, 0.3 g MTBHQ, 0.30 g N, N, N′, N′-tetramethyl-1,6-hexane diamine and 0.03 g DBTL were added. The solution was cooled to 70° C., and 58.7 g of hexamethylene diisocyanate was added in 2.5 hours. Thirty minutes after the addition was finished, the toluene was removed by vacuum distillation at 125° C. to yield solid urethane acrylate.
