N2 - In the TGA experiments, the activation energy (25-30 kcal mol-1) and preexponential constant (ln A = 34.6 h-1) of the pyrolysis of PU/CFCs wastes were obtained. At least three discrete features at 328, 423, and 443 K are observed corresponding to desorption of CFC-141b from external, internal, and crosslink of the PU matrix, respectively. It indicates that pyrolysis of the PU polymer (at elevated temperatures) may not be effected by the presence of CFCs. In a single pass through the heated sodium oxalate bed (573 K) caused a nearly complete mineralization of CFC-141b.
