ABSTRACT
New poly(urethane-sulfone)s networks were prepared by the [3 + 2] dipolar cycloaddition of azidomethyl polyethersulfone to urethane-bismaleimides based on various polyols different by their structure and molecular weight. The chemical structure of these polymers was confirmed by the Fourier transform infrared and nuclear magnetic resonance spectroscopy. The new polymers were characterized using thermogravimetric analysis, differential scanning calorimetry, dynamic mechanical analysis, as well as by stress-strain and water contact angle measurements.
