PHASE STABLE COMPOSITIONS CONTAINING A PARAFFINIC POLYOL AND AN ISOCYANATE REACTIVE PREPOLYMER Abstract of the Disclosure Phase stable compositions containing a paraffinic polyol chain extender, e.g., 1,4-butanediol, and an isocyanate-reactive prepolymer containing hydroxy and epoxy groups are formed by heating the polyol and pre- polymer in the presence of one another to yield the phase stable composition. The composition, when re- acted with a polyisocyanate, yields poly(oxazolidone/ urethane) thermoset compositions.
