Abstract:
Rheo-optical Fourier-Transform IR spectroscopy was applied to study the transient structural changes of S-crosslinked natural rubber during stress-relaxation at different stress levels. From these measurements, the predominant mol. consequences of the obsd. stress-relaxation are a substantial improvement of amorphous chain alignment and a less significant increase of the extent and orientation of the strain-induced crystal phase.
