실험 절차

A 250 mL flask was charged with 19.4 grams (0.10 mol) of 1,3-bis(isocyanatomethyl)cyclohexane under dry nitrogen flow and heated to about 64° C. under positive nitrogen pressure. To this reaction mixture, 2 drops of catalyst dibutyltin dilaurate were added. A mixture of 10.5 grams (0.047 mol) of 2-hydroxy-3-phenoxypropyl acrylate and 16.15 grams (0.139 mol) of 2-hydroxyethyl acrylate containing 0.05 grams of BHT as an inhibitor was prepared and added over a period of one hour and 25 minutes while the reaction temperature was maintained between 64° C. and 75° C. After the addition of 90% above mixture, 1.6 gram (0.014 mol) of 1,2-diaminocyclohexane was added before the final addition of remaining 10% above mixture. After about another 5 hours stirring, the heat was turned off, and monomer was collected from the flask as viscous yellow tint liquid and stored in a dry atmosphere.
