ABSTRACT:
The instant invention relates to the preparation of stable, relatively low viscosity dispersions of polyisocyanate-polyaddition products in hydroxyl containing compounds as dispersing agents. The process broadly comprises mixing an aqueous dispersion of an isocyanate-polyaddition product with a compound having at least two hydroxyl groups and having a boiling point about 100.degree. C., and thereafter at least partially distilling off the water.
