Abstract: The effect of various stabilizers on the thermo-oxidative stability of PET was investigated using isothermal and dynamic thermogravimetric analysis (TGA) in the presence of oxigen. From the kinetic analysis of the thermo-oxidative process it was found that the material decomposes via an autocatalytic mechanism. Addition of stabilizers leads to a delay of degradation as suggested by the higher activation energies and pre-exponential factors obtained from the polymer samples containing stabilizers.
