Paper Abstract

The potential of rhea-optical Fourier-Transform infrared (FTIR) spectroscopy is demonstrated with reference to the characterization of segmental orientation during cyclic elongation-recovery procedures of poly(ether-ester)amides based on chain-extended polyamide 12 (hard segments) and oligotetrahydrofuran (soft segments). The rheo-optical data show that the soft and hard segments deform by different orientation mechanisms. Thus, the soft segments exhibit positive chain alignment during loading and desorientation upon unloading. The deformation of the hard segments is characterized by an initial transverse orientation with a subsequent reorganization of their morphology.
