Abstract
over 240 °C, tensile strength between 28.1-47.3 Mpa, elongation at break above 1000%, Young's modulus between 13.8-32.7 Mpa and resilience at 200% fixed-length between 70-90%, which makes them a promising alternative to products synthesized through the isocyanate route. In addition, the effects of the hard segment contents and the molecular weights of soft segment on the properties of TPCUEs are researched.
