Abstract:
A process for producing high molecular polyurethane compounds having wide uses as coating materials, resins and foams. The high molecular compounds are produced by reacting an oxadiazinone compound, which has been obtained by the reaction of an organic isocyanate compound with carbon dioxide, with a polyol compound in the presence of a catalyst of such a specific organotin compound as tetrabutyl-1,3-diacetoxydistannoxane.
