Abstract  

The kinetic parameters for the thermal degradation of high impact polystyrene (HIPS) in presence of some metal oxides exhibit reaction rate compensation effect. In thermal degradation of HIPS in presence of transition metal oxides different active centers act simultaneously as reaction sites and macroradicals are formed through random chain scission, disproportion or cyclization. Some oxides retard the polymer degradation through crosslinking and cyclization by the interaction of macroradicals with the double bond in butadiene.
