Paper Abstract

Polarized Raman micrbprobe spectra of spin-oriented, as well as spun and drawn, single filaments of polyethylene terephthalate have demonstrated the development of both orientation and crystallization with take-up speed (TUS) and conditions of drawing1-. Careful examination of those spectra indicated the presence of overlapping bands in the carbonyl and glycol regions. By using commercially available band-fitting software2 we have succeeded in separating carbonyl band components and correlating them with different atomic arrangements of the polymer.
