Sažetak
The process of thermal degradation of poly(vinyl- chloride)/poly(methylmethacrylate-butadiene- styrene) (PVC/MBS) blends was investigated by means of isothermal thermogravimetry in nitrogen . The total mass loss was determined after 120 min. The kinetic parameters of degradation process were determined applying two kinetic models: the model which assumes the autocatalytic degradation (Prout-Tompkins) and the model of twodimensional diffusion. It was established that the thermal degradation at lower degrees of conversion ( alpha < 0, 20) was well described by the former model, but the latter model was applicable in the area of higher degrees of conversion. The thermal stability of blends at a certain temperature of isothermal degradation depends on the blend composition and the shell /core ratio in MBS and on the adhesion in the boundary layer in PVC/MBS blends.
