Abstract:

In order to obtain thermoplastic polyurethane elastomers (TPUEs) with good thermal and mechanical properties, in this work, poly(ether carbonate) polyurethane elastomers (PECUEs) with mixed soft segments are synthesized using a non-toxic, non-polluting and simple process of melt polycondensation. Thermal and tensile tests show that PECUEs are elastomers with excellent low-temperature elasticity and mechanical properties (e.g., T_g of − 36 °C, T_d,5% of 284 °C, tensile strength of 36.1 Mpa, elongation at break of 1308% and resilience at 200% fixed length of 90%). This work is the first to synthesize PECUEs by melt polycondensation process. The products have good performance, green process and great potential for industrial applications.
