説明

For the purpose of elucidating the mechanism of thermal degradation of polyvinyl alcohol (PVA), the compositions of degradation products of PVA were investigated. Infraredspectra and elemental analysis of the PVA film treated in vacuo did not differ greatly from those of the original. In the presence of air, it colored considerably and showed a significant increase in intensity of the absorption band due to >C=O.<BR>Acetaldehyde, crotonaldehyde, benzaldehyde, acetophenone and water were indentified in the degradation products of powdered PVA in vacuo, in nitrogen and in air, the quantities of these compounds being different. The presence of phenolic compounds were also inferred.The residue obtaind in the thermal degradation of powdered PVA in vacuo colored, and showed the decrease in-OH band and increase in >CO band, the results being different from those of the film. The elemental analysis were greatly different from those of the original.
