영문 초록

PVA is useful for the production of water-soluble packaging, paper, textile sizes. Algin is known as natural polymer from marine plants. Algin was blended with PV A in different ratios by solution blending technique to give degradability polymer. Miscibility behavior between PVA and Algin has been studied with DSC and morphological changes by SEM. PVA/Algin blend films were observed to be partially miscible by DSC and SEM. As a result, Blend films were completely degraded with the passage of time in the buff er solution of pH. With β-glucosidase, the rate of degradation of blend films were rapidly better than pH solution by enzymosis.
