反応手順
69 parts of vinyl isocyanate and 70 parts of ethyl acetate are initially taken in a reaction vessel equipped with a high-efficiency condenser (with cooling brine), a stirrer, a thermometer and a feed Vessel. 74 parts of tert.-butanol, 73 parts of ethyl acetate and 0.01% of dibutyl-tin dilaurate are added in the course of 1 hour at 40° C., after which the mixture is allowed to react for a further 10 hours at this temperature. A pale yellow clear solution is formed. Content of blocked isocyanate groups: 14.7%.
