Abstract

Raman and IR spectroscopy were used to examine polyvinyl alcohol (PVA) thermally treated in air or vacuum. It was found that after several hours of treatment in air at 470 K bands in Raman spectrum disappear. After vacuum treatment some bands disappear and other become stronger, and slightly change their positions. Such a phenomenon is attributed to the increase of molecular polarizability along polymer chain caused by conjugation.
