- Abstract
The thermal behavior of poly(methyl methacrylate) (PMMA) was studied in the presence of AlBr3 using TG-DTA-DTG, IR and Py-GC-MS techniques. Degradation products were identified. It was found that PMMA started degrading at a lower temperature due to the generation of free radicals (Br•), being the product of decomposition of AlBr3. Despite early destabilization of the system, stabilization zone was also highlighted. Flammability test was conducted to check the affectivity of AlBr3. Degradation mechanism has been proposed. Pyrolysis of the system (PMMA–AlBr3) was also monitored by heating it at different temperatures.
