실험 절차

143.1 g of Rucoflex XS-5570-55, 154.4 g of Rucoflex S-1011-55, 9.0 g of MPdiol and 6.7 g of DMPA are reacted with 73.2 g of TMXDI and 25.2 d of HDI at 80° C. for 3 hours to prepare a prepolymer. The prepolymer is then dispersed in a solution of 3.0 NaOH and 2.75 g of EA in 736 g of water. After 5 minutes, a solution of 2.7 g of EDA and 3.06 g of DETA in 50.0 g of water is added to form a aqueous poly(urethane/urea) dispersion. A finely divided dispersion having solids content of 35.2% and a pH of 7.85 is obtained.
