실험 절차

113 parts of ε-caprolactam and 91 parts of ethyl acetate (+0.015% of dibutyl-tin dilaurate) are introduced into a reaction vessel and the mixture is heated to about 50° C. A mixture of 69 parts of vinyl isocyanate and 91 parts of ethyl acetate is then added dropwise in the course of 1 hour, after which the mixture is allowed to react for 5 hours. A pale yellow clear solution is obtained. Blocked isocyanate content: 11.5%.
