A series of polyurea urethanes was isothermally synthesized from toluene diisocyanate (TDI), water, and trifunctional poly(propylene oxide) in the temperature range of 50 -150Β°C. Morphologies of the samples vary significantly as a function of reaction temperature. In this system, phase separation co
