Abstract : The patent describes a process for preparing polyoxazolidones. A polyepoxide is reacted with a polyisocyanate in the presence of a catalytic amount of an organic phosphonium halide. The polymer products so produced can be used in a variety of applications, such as coatings, castings, molding compositions, adhesives, filament winding, sealant and calking compounds, potting compounds, impregnating compounds, and the like.
