Fourier transform infra-red (FTi.r.) spectroscopy was used to investigate the orientation of uniaxially stretched films of poly(vinyl phenol) (PVPh). The angles of the various vibrations were determined with respect to the CH2""CH2 axis. No evidence was found for any influence of the hydrogen bonds on the orientation of PVPh when compared to polystyrene (PS). On the other hand, it was noted that, upon formation of hydrogen bonds, the ~ angle of the hydroxyl groups changes from 26 to 65 °.
