The infrared spectra of the films of syndiotactic‐rich poly(vinyl alcohol) ( s ‐PVA) prepared by the casting, frame, and bubble methods were obtained. The band at 705 cm −1 decreased with the increased inclination of the film plane to the direction of the irradiation of infrared rays and was related to the orientation of the molecules in the adsorbed phases of both sides of film.
