摘要
It has been found for polyoxymethylene that differences in morphological structure cause remarkable frequency changes for some infra-red-active vibrational modes. In relation to this phenomenon, the vibrational spectra of poly(ethylene oxide) were investigated on two samples with different morphologies, a well drawn film and a solution-grown lamellar crystal. The A2 bands of the solution-grown crystal shifted towards the high-frequency side, while the other bands, A1 and E1, remained at the same positions as those of the drawn film. It was concluded that the spectral change is due to the same mechanism as in polyoxymethylene. © 1990.
