摘要
We investigated the structure and viscoelastic properties of a series of poly(ether-block-amide) thermoplastic elastomers consisting of hard polyamide segments and soft polyether segments with no ester linkages. All thermoplastic elastomers used in this study exhibited heterogenous morphologies with crystalline lamella in the solid state. The heterogeneities and solubilities in the amorphous regions of the elastomers depended on the sample composition. We did not observe a clear, slow relaxation mechanism characteristic of phase-separated liquids for the dynamic moduli of samples in the molten state. This result shows that the melted samples had a homogeneous structure due to the good miscibility between the poly amide and polyether segments.
