ABSTRACT:
A process is described for the preparation of urethane prepolymers from hydroxy-terminated diene polymers and normally liquid, relatively non-volatile, aromatic polyisocyanates. The prepolymers are made at a temperature above about 150.degree. C. to provide urethane prepolymer products that resist the tendency to form multiple phases or layers upon storage at room temperature.
