Two kinds of poly(vinyl alcohol)(PVA) films iodinated in solution before casting (IBC) with weight gains of 100%(slightly crystalline) and 150%(completely amorphous) were drawn at room temperature. Iodine was eliminated by immersing the films in sodium thiosulfate solutions in ethylene glycol(EG)/water and N-methylformamide(NMFA) followed by washing and drying. The degree of swelling of undrawn film on deiodination was lower and the deiodination time was longer in the NMFA solution than in the EG/water solution. All the undrawn films after deiodination and drying exhibited considerable and mutually similar crystallinity. While a major portion of the crystallization occurred in the course of drying after immersing in the EG/water solution, the larger half of the crystallization occurred in the course of immersing in the NMFA solution. Drawability of the IBC film was very high even at room temperature to readily produce a draw ratio of 8. The degree of swelling of the drawn film on deiodination decreased continuously and the deiodination time increased and then decreased with increasing draw ratio. The degree of swelling and the deiodination time were relatively low and long, respectively, when the NMFA solution was used as solvent. The crystallinity, orientation, initial modulus of the drawn films after deiodination and drying increased with draw ratio, and was relatively high when the NMFA solution was used as solvent and the weight gain were lower.
