Thermal decomposition of poly-ethoxyethyl methacrylate and poly-methyl methacrylate studied by the method of thermogravimetry. Both samples were obtained free radical polymerization to high conversion in the presence of azo dinitrile isobutyric acid. Thermal activation energy calculated by Friedman and OFW methods depends on the degree of decomposition of poly-methyl methacrylate and poly-ethoxyethyl methacrylate. . The activation energy of the thermal decomposition of poly-methyl methacrylate changes on the degree of decomposition. For poly-ethoxyethyl methacrylate, depolymerized as poly-methyl methacrylate, within the measurement error to separate the individual stage thermal failed, the activation energy of its thermal decomposition in 1.5-2,5 times lower activation energy of the thermal decomposition of poly-methyl methacrylate at the same rate of decay.
