Reaction Steps
286.2 g of Rucoflex XS-5570-55, 675.0 g of Rucoflex S-1011-35 and 20.1 g of DMPA are reacted with 116.6 g of IPDI and 44.1 g of HDI at 80° C. for 2.5 hours to prepare a prepolymer. The prepolymer is then dispersed in a solution of 8.4 g of NaOH and 4.8 g of EA in 2114 g of water. After 10 minutes, a solution of 4.7 g of EDA and 5.4 g of DETA in 150.0 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 7.3 is obtained.
