実験手順

Into a reaction vessel fitted with a stirrer and gas inlet tube is placed one mole (222 g) of isophorone diisocyanate. To the reaction vessel was next added 0.2% by weight of dibutyltin dilaurate catalyst and 0.05% by weight of phenothiazine based on the total weight of reactants. The mixture is then blanketed with dry nitrogen gas and one mole (116 gram) of 2-hydroxyethyl acrylate is added over a period of from 4 to 5 hours while maintaining the temperature in the range of 25°-30° C., cooling being used when needed. This temperature is maintained for one hour after acrylate addition is complete.
