Influence of uniaxial deformation of colored polyvinyl alcohol films on their thermal-oxidative destruction

The thermal-oxidative destruction of films made of polyvinyl alcohol colored by brilliant yellow and subjected to uniaxial deformation was studied by the thermogravimetric method. The intensive dehydration of polyvinyl alcohol begins at temperatures higher than 150°C in non-deformed films and higher...

Summary:The thermal-oxidative destruction of films made of polyvinyl alcohol colored by brilliant yellow and subjected to uniaxial deformation was studied by the thermogravimetric method. The intensive dehydration of polyvinyl alcohol begins at temperatures higher than 150°C in non-deformed films and higher than 220°C in samples subjected to the uniaxial extension. The dye practically does not influence thermal-oxidative destruction of non-oriented samples. The stretching and treatment by a “cross-linking” agent during the uniaxial deformation of the film increases its thermal stability.
