| Abstract: | The effects of the synthesis process,soft segment type,rigid segment content and R value,etc.of TODI-based thermoplastic polyurethane elastomer（TPU） on its properties were briefly investigated.And its kinetic mechanical properties were compared with those of MDI-based TPU.The results show that the poly（ε-caprolactone）（PCL）-based TPU prepared by the prepolymer process possesses good performance.The increase of the rigid segment content and R value within a certain range can improve the mechanical properties of the materials.Compared with the MDI-based TPU,the storage modulus（E＇） of TODI-based TPU has a smaller decline at high temperature. |
