| 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.
