An Investigation of Thermal Degradation of Poly(Lactic Acid)
نویسندگان
چکیده
Thermal degradation of poly(lactic acid) (PLA), a biodegradable and bioabsorbable polyester, has been investigated under inert atmosphere using both isothermal and dynamic heating regimes.. Two kinetic models, one for isothermal and the other for dynamic heating regims were used to fit the experimental data. It has been demonstrated that the thermal degradation of PLA is a one-stage process within the range 0-30% of weight loss, having activation energy of 21-23 kJ/mol.
