Abstract
The instant invention relates to the use of stable, relatively low viscosity dispersions of polyisocyanate-polyaddition products in hydroxyl containing compounds as dispersing agents in the preparation of polyurethane resins. The dispersions are made by a process which 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.
