Abstract
Liquid hydroxyurethane products having cyclocarbonate end groups are prepared by reacting a molar excess of a bis-carbonate of a bis-glycidyl ether of neopentyl glycol or 1,4-cyclohexanedimethanol with a polyoxyalkylenediamine such as a polyoxypropylenediamine. These products are useful for the preparation of polyurethanes, polyurethane polyols, polyester polyurethane polyols, and polycarbonate polyurethane polyols.
