실험 절차

69 parts of vinyl isocyanate and 89.5 parts of ethyl acetate are initially taken in a reaction vessel and are heated at 40° C. A mixture of 110 parts of cyclohexanol, 89.5 parts of ethyl acetate and 0.02% of dibutyltin dilaurate as the catalyst is added in the course of one hour, after which the mixture is allowed to continue reacting for a further 2 hours at 40° C. A pale yellow solution is obtained, from which, on cooling, the reaction product separates out in the form of crystals. Content of blocked isocyanate groups: 11.7%.
