Abstract
Polyethyl methacrylate /PEMA/ containing ferric chloride was prepared by free radical polymerization at 70°C. Mössbauer studies of the polymer heated at 150°C, 300°C and 500°C for 1 h showed that during the thermal degradation the Fe3+ species are reduced to Fe2+ and the final form is α-Fe2O3. TGA studies showed that the addition of ferric chloride during the polymerization of ethyl methacrylate increased the thermal stability of PEMA by 40°C. The final decomposition temperature /FDT/ increased by 75°C.
