실험 절차

A mixture of 0.0027 mol of alcohol and 0.00284 mol of isocyanatoethyl methacrylate, 20 mL ethyl acetate, and two drops of dibutyltin dilaurate were added to a polymerization bottle with a stirrer. At room temperature the solution was stirred for 2 days. The solvent was then evaporated, and the solid was redissolved in acetone and precipitated from water. The collected solid was dissolved in ethyl acetate and washed by water and sodium carbonate, and dried by anhydrous magnesium sulfate. Evaporation of solvent by a rotary evaporator gave the desired urethane methacrylate.
