POLARISED CONFOCAL RAMAN MICROSCOPY

Applied Spectroscopy 52, No.12, Dec.1998, p.1498-504 MEASUREMENT OF ORIENTATION AND CRYSTALLINITY IN UNIAXIALLY DRAWN POLY(ETHYLENE TEREPHTHALATE) USING POLARISED CONFOCAL RAMAN MICROSCOPY Everall N J... 

Polarised confocal Raman microscopy was used to measure molecular orientation in uniaxially drawn PETP films, prepared with draw ratios from 1 to 3.5. The orientation of both polarised Raman microscopy and polarised attenuated total reflection IR spectroscopy. Crystallinity profiles were measured through the thickness of the film samples and compared with the orientation gradients existing in the films. This procedure was to determine whether the intuitive assumption that orientation and crystallinity would be positively correlated actually holds true on the microscopic scale for these samples. 18 refs.
