The process requires the combination of a soluble polyol with a di- or polyisocyanate under densified fluid conditions. The process to prepare a waterborne polyurethane involves the utilization of a polyol containing ionic or latent ionic groups which must undergo preneutralization before combining with the di- or polyisocyanate under densified fluid conditions. The resulting polyurethane is substantially free of an organic solvent.
