Photocatalytic Degradation of Polyvinyl Chloride-Vinyl acetate Film Using 5-Phenylazo Salicyaldehyde Derivative

Abstract

      Polymers are employed in a variety of applications that may be harmful to the environment. As a result, the purpose of the research is to dismantle the mutated polymers by inexpensive materials to preserve the environment. To do this, an azole ring in 5-phenylazo salicalicaldehyde derivative was produced and put into a poly (vinyl chloride-vinyl acetate) (PVC-VA) chain by substitution process. The final product was created by adding 5-phenylazo salicalicaldehyde to the priority chemical. Under ultraviolet light irradiation in accelerated settings, the films' resistance to deterioration and IOH,ICO,IC=C were examined using Fourier-transform infrared spectroscopy, viscosity tests , and weight loss to follow the changes caused by UV radiation exposure. The azo compound significantly improved the photo degradation of PVC-VC polymer. When compared to the original polymer.
