Polyvinyl alcohol in the form of film and powder were irradiated in air by gamma rays from a Co⁶⁰ source, and by deuterons accelerated by a cyclotron. Weight changes, viscosity, solubility, and infrared absorption spectra of irradiated samples were measured as a function of absorbed dose. The reduction of the molecular weight of the irradiated specimens was observed suggesting that the effect was one of degradation. Infrared absorption spectra showed the formation of the carbonyl groups in the irradiated specimen.
