The first peak of the PVA in Fig. 7 corresponded to the loss of water.The other peaks corresponded to the total decomposition of the polymeric structure. The three peaks in the temperature range of 190–280 ◦C, were responsible for the glass transition temperatures and the melting point of the PVA.The CG showed a weight loss in three
stages, the first stage of the CG from the TGA occurred in the range of 30–200 ◦C and the %weight loss of 9.33% was probably due to a loss of moisture from the samples. The results corresponded to those of previous work
