반응 단계
In another reactor, a fully blocked diurethane of 80/20 2,4/2,6-toluene diisocyanate mixture was prepared by slowly adding 87.1 parts of 80/20 toluene diisocyanate to 142 parts of 2-ethylhexanol containing 1 drop of dibutyl tin dilaurate with external cooling to maintain the reaction mixture below 100°C.
