| Abstract: | Cadmium adipate and cadmium oxalate suitable for use as stabilizer for vinyl polymers were prepared by metathesis in aqueous alcohol solutions. The thermal stability of the carboxylates was measured gravimetrically at 443, 453 and 463K. Both cadmium adipate and cadmium oxalate showed less than 20% in weight indicating that they are relatively stable within this temperature range. Kinetic studies of the thermal decomposition of the dicarboxylates showed that the initial rate constant for the decomposition of cadmium adipate is higher than that of cadmium oxalate and they are of the order of magnitude of 10-2 min-1. The enthalpy, entropy and free energy of activation for the decomposition of the metal dicarboxylates were also determined. |
