Abstract
Infrared absorption spectra of ethylene glycol and various higher molecular weight poly(ethylene oxides) have been obtained both in the liquid and solid phases. The similarity of the solid and liquid phase spectra for the poly(ethylene oxides) suggest that these materials exist in essentially the same conformation (gauche) in both phases. The disappearance of a band similar to one in liquid ethylene glycol with increasing molecular weight suggests a molecular weight dependence of a trans conformation. Oriented high molecular weight poly(ethylene oxide) spectra are consistent with recent x‐ray diffraction studies.Keywords
