반응 단계
0.5 g of dibutyltin dilaurate was added to a 60% strength by weight solution of 105 g of toluylene diisocyanate and 170.0 g of diphenylmethane 4,4'-diisocyanate in tetrahydrofuran, and the mixture was then heated to 60° C. At this temperature, a 60% strength by weight solution of 345 g of a polyesterol obtained from 1,4-butanediol and adipic acid and having a molecular weight of 1000, 1267.0 g of a polyesterol obtained from 1,6-hexanediol, adipic acid and terephthalic acid, 3.17 g of trimethylolpropane, 4.76 g of methyldiethanolamine, 72 g of diethoxylated bisphenol A and 25.1 g of 1,6-hexanediol in tetrahydrofuran was metered in over 2 hours.
