The Influence of the Structure Peculiarity of the Polyvinyl Alcohol Structure on the Direct Blackening Photostimulated Processes in the Polyvinyl Alcohol-zink oxude-bismuth Chloride Composition

In presented paper, we will investigate the photosensitivity of a composition which consists of a polyvinyl alcohol, zinc oxide and bismuth chloride (PVA-ZnO-BiCl3). Advanced, is an experimental result of the dependence between the photosensitivity of a similar system and the content of the acetate groups in the polymer structure, and its explanation.
