Polyvinyl alcohol-glycerol (PVA-G) and polyvinyl alcohol-D-sorbitol (PVA-D) polyblends were obtained by blending polyvinyl alcohol with different molecular weights (PVA17 and PVA24) and plasticizers (glycerol and D-sorbitol) in various blended ratios through melting process.Furthermore, the various plasticizers and contents effects on the characteristics of polyvinyl alcohol were investigated.
