Research on Properties of Poly(ether Carbonate) Polyurethane Elastomers with Mixed Soft Segments Synthesized Via Melt Polycondensation Process

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., Tg of − 36 °C, Td,5
