✦ Synopsis

Akstract--From measurements of weight losses of samples of isotactic polypropylene (IPP) with triphenylphosphonium cyciopentadienylide (TPCP) under various conditions and from the measurements of time courses of chemiluminescence, kinetic parameters of the process were determined. At concentrations of TPCP > 1 wt~, the rate of loss of weight changes with the additive concentration. Compensation of the values of activation energy and pre-exponential term, determined from thermo-oxidation of IPP alone and IPP with TPCP, indicates that interaction of TPCP with oxidized polymer is complex.

## Abstract Ammonium sulfate was compounded into polystyrene (PS) to modify thermal degradation of PS. At elevated temperatures, ammonium sulfate decomposes into ammonia, sulfuric acid and further into sulfur trioxide and water. The aim of the study was to investigate how these acidic and oxidizing
