Abstract
Provided is a thermoplastic polyether ester elastomer composition having a first chain represented by the following Formula (I) and a second chain represented by the following Formula (II), which are connected to each other:Wherein, the melting point of the thermoplastic polyether ester elastomer composition ranges from 80° C. to 160° C., and the enthalpy of fusion of the thermoplastic polyether ester elastomer composition is greater than 6 J/g. Production of the thermoplastic polyether ester elastomer composition has low energy consumption and facilitates smooth cutting strands into pellets, which is beneficial to mass production of the thermoplastic polyether ester elastomer composition.
