실험 절차

Tolylene diisocyanate (2,4-tolylene diisocyanate/2,6-tolylene diisocyanate=80/20, hereinafter referred to as "TDI", 174 g) and EGA (130 g) are mixed, and to the stirred mixture is added dropwise HEMA (130 g, wherein phenothiazine (0.13 g) is dissolved) under nitrogen gas at 20°-45° C. over a period of 1 hour. After finishing the dropping of HEMA, the mixture is heated to 60° C. in 30 minutes and is stirred at the same temperature for 1.5 hour. It is confirmed that the product contains NCO of 9.6% (measured by di-n-butylamine-hydrochloric acid titration method) and an isocyanate product semi-blocked with HEMA is produced.
