Anisotropy of polarizing polyvinyl alcohol films

Abstract

The anisotropy ofthe polarizing films produced on the base of polyvinyl alcohol and dichroic dyes has been studied by visible dichroism and heat conductivity anisotropy methods. The influence ofstructure and content ofthe dye as well the stretch ratio of films on the orientation factors has been investigated. The comparative results allowed to evaluate a degree of arrangement of polymer chains and dye molecules in anisotropic films.
