反応手順
190.8 g of Rucoflex XS-5570-55, 102.9 g of Rucoflex S-1011-55 and 6.7 g of DMPA are reacted with 48.8 g of TMXDI and 18.8 g of HDI at 80° C. for 3 hours to prepare a prepolymer. The prepolymer is then dispersed into a solution of 3.0 g of NaOH and 1.83 of EA in 650 g of water. After 10 minutes, a solution of 4.08 g of DETA in 50.0 g of water is added to form an aqueous poly(urethane/urea) dispersion. A finely divided dispersion having a solids content of 35.1% and a pH of 7.05 is obtained.
