|Abstract:||The thermal stability of bromobenzylated poly(2,6-dimethyl-1,4-phenylene oxide) (BrPPO) in a nitrogen atmosphere was studied by thermogravimetry. While PPO is thermally stable up to 673 K, BrPPO begins to degrade at 490-540 K, depending on the degree of bromination. The weight loss of BrPPO in the first degradation stage also depends on the degree of bromination. The activation energy for the first degradation stage is about 185 kJ mol-1 for BrPPO with a degree of bromination of 50% or less and about 110 kJ mol-1 for BrPPO with a higher degree of bromination. © 1987.|
