Effect of Chain Extender and Banana Fiber on Melt-Processing Properties of Poly (vinyl alcohol)
This research aims to study the effect of chain extender and banana fiber on melt processing of poly (vinyl alcohol). 0 and 5 %w/w of banana fiber and 0, 2 and 4 %w/w of chain extender were melt-blended with poly (vinyl alcohol) in an internal mixer at 200°C. The blended materials were then injected...

| description | This research aims to study the effect of chain extender and banana fiber on melt processing of poly (vinyl alcohol). 0 and 5 %w/w of banana fiber and 0, 2 and 4 %w/w of chain extender were melt-blended with poly (vinyl alcohol) in an internal mixer at 200°C. The blended materials were then injected into a mold to produce tensile specimens. It was found that chain extender increased elongation at break, tensile strength and tensile modulus because it connected poly (vinyl alcohol) molecules together as verified by structural analysis from FTIR results. Chain extender also caused increased the thermal stability of poly (vinyl alcohol) as analyzed by TGA technique. Furthermore, banana fiber could
reduce elongation at break but increase tensile strength and modulus of poly (vinyl alcohol). |
