Resum
An enhanced general analytical equation has been developed in order to evaluate the kinetic parameters of the thermal degradation of poly(lactic acid) (PLA) at various linear heating rates and at constant rate conditions. This improvement consisted of replacing the n-order conversion function by a modified form of the Sestak-Berggren equation f(a) = c(1-a)nam, which led to better adjustment of experimental data, and also adequately represented the conventional mechanisms for solid-state processe...
