반응 단계
113 parts of ε-caprolactam, 91 parts of ethyl acetate and 0.015% of dibutyl-tin dilaurate are initially taken in a reaction vessel and are heated at about 50° C. A mixture of 69 parts of vinyl isocyanate and 91 parts of ethyl acetate is added dropwise in the course of 1 hour, after which the mixture is allowed to continue reacting for a further 5 hours. A pale yellow clear solution is obtained. Content of blocked isocyanate groups: 11.5%. Preparation of component (C)
