Notes:
It is found from polarized infrared spectroscopy that treatment of oriented poly(ethylene terephthalate) (PET) film with strongly interacting solvents such as s-tetrachloroethane, nitrobenzene, dimethylformamide, and benzyl alcohol results in disorientation of polymer chains. Partial transformation from trans to gauche conformation takes place on thermal treatment and, to a larger extent, on solvent treatment. Increasing sharpness of the 988 cm-1 band on solvent treatment indicates the formation of regular chain folds. Some new spectral features are discussed.
