Reaction Steps
143.1 g of Rucoflex XS-5570-55, 154.5 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 in a solution of 3.0 g of NaOH and 1.83 g of EA in 650 g of water. After 5 minutes, a solution of 1.8 g of EDA and 2.04 g of DETA is added to form an aqueous poly(urethane/urea) dispersion. A finely divided dispersion having solids content of 35.2% and a pH of 7.1 is obtained.
