Procedure

The reaction mixture was emulsified as follows: 300 g polycarbodiimide solution as prepared above was heated to 65° C. and added to a hot aqueous solution of Ethoquad™ C-12 (2% on solids), Tergitol 15S30 (3% on solids) and Tergitol™ TMN-6 (5.4% solids). 199 g water was added. The mixture was emulsified with 2 stage lab Manton-Gaulin at 220/20 bar (2 passes). The solvent was stripped off with a Büchi evaporator, using water jet vacuum. A stable, milky dispersion of 21.9% solids was obtained.
