We have been investigating a method for obtaining a poly(ethylene terephthalate) (PET) film with high heat resistance by immersing an amorphous film (APET) in a solvent, followed by stretching, and allowing the stretching temperature to be higher than the glass transition temperature. Furthermore, it has already been reported that ethyl acetate shows an effect for solvent-induced crystallization of APET to improve the heat resistance property. In this study, solvent crystallization of APET was carried out in various organic solvents with a carbonyl group, such as ethyl formate, N,N-dimethylformamide (DMF), and γbutyrolactone, in addition to ethyl acetate, and was evaluated by the attenuated total reflectance (ATR) measurement of the immersed films. The results indicated that the lactone, γbutyrolactone, has a significant effect on crystallization.
