Thermal Degradation Behavior And Kinetic Analysis Of Biodegradable Polymers Using Various Comparative Models, 1 - Poly(Butylene Succinate)

Thermal degradation behavior of a biodegradable polymer (PBS) has been investigated by conventional and MTGA methods. The kinetic parameters of degradation were calculated by a general analytical solution and by the Coats-Redfern, Ozawa, Horowitz-Metzger, and MTGA methods. The results reveal that the reaction mechanism at lower temperature is probably the F1 model through the reaction of random chain cleavage via cis-elimination. However, the reaction mechanism at higher temperature is likely to be D1 model because of the dominant diffusion control effect.
