N/A Algin is known as biodegradable natural polymer from marine plants. PVA/Algin blend films were prepared by solution blending method for the purpose of useful biodegradable polymer. Characteristics properties of PVA/Algin blend films such as DSC, Elongation, Tensile strength and Morphological change by SEM were ratio of Algin. PVA/Algin blend films were found that phase separation was occured as more than 25wt% increasing the blend ratio of Algin. Blend films were observed to be less partially compatibility than 10wt% increasing the blend ratio of Algin by DSC, mechanical properties and SEM. Also, PVA/Algin blend films at the laboratory soil test(Pot Test) were completely degraded in months with four kinds of soils by microorganisms.

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.
