Spectroscopic elucidation of structure-property relations in filaments melt-spun from amorphous polymers

摘要: Abstract Melt spinning and drawing of amorphous cyclo-olefin co-polyamide polymeric materials were performed to develop mono-component continuous filaments. Raman spectroscopy was employed assess the effect a static bending deformation on microstructure Spectra stemming from fiber regions under tensile compressive loading do not show any appreciable shift their vibrational bands as function applied strain. The bent filaments manage redistribute strains without stretching or buckling polymer chains associated with peak shifting in spectrum. influence draw ratio degree molecular ordering demonstrated by means polarized spectroscopy. An increase leads variation polarization for spectroscopic located along backbone. We observed correlation between these macroscopic modulus material.
