Abstract: Studies performed to optimize the polarization ability of polyvinyl alcohol systems have revealed the effect of iodine concentration on spectral and polarization characteristics of thinfilm polarizers. The time of treating the polyvinyl alcohol film in the potassium iodide solution has been determined, which is optimal in view of obtaining optically transparent polarizers with the polarization degree of about 95–99%.

Keywords: polyvinyl alcohol, polarizers, polarization degree, iodization, potassium iodide.
