Synthesis of Biodegradable Polylactic Acid Polymer By Using Lactic Acid Monomer (original) (raw)

Biodegradable polymer polylactic acid was synthesized by using lactic acid. FT-IR technique was used for confirmation of LA and PLA. Thermal behavior of PLA was carried out using DSC analysis. DSC thermogram of PLA showed Glass Transition temperature (Tg) at 58.0 ̊C, endothermic peak at 119.4°C and Sharp exothermic peak at 151.7°C. PLA Film was prepared by using solvent casting method. The biodegradability of the PLA Film was checked by soil burial test in laboratory for 200 days observation period.
