The kinetic constants of the process were determined. The heating rate of the sample varied over a wide range and amounted to 2, 5, 8, 20, 35 and 50 K/min. The values of the kinetic constants of PMMA decomposition were determined using the isoconversional method. For the degree of conversion of the substance from 10 to 90%, the values of activation energy for the thermal decomposition of PMMA vary in the range from 213.5 to 194.3 kJ/mol, and the values of the pre-exponential coefficient change in the range from 1.62 ⋅ 10<sup>16</sup> to 6.85 ⋅ 10<sup>12</sup> 1/s. The average activation energy for the thermal decomposition of PMMA in a carbon dioxide flow was 206 kJ/mol.</p></abstract><trans-abstract xml:lang="ru"><p>Методом термогравиметрического анализа определены кинетические константы термического разложения полиметилметакрилата в потоке углекислого газа в широком диапазоне скоростей нагрева образцов (2–50 К/мин). Значения кинетических констант разложения определены по методу постоянных степеней превращения. Показано, что для степеней превращения вещества от 10 до 90% значения энергии активации термораспада ПММА изменяются в диапазоне 213.5–194.3 кДж/моль, а значения предэкспоненциального коэффициента – в диапазоне 1.62 · 10<sup>16</sup>– 6.85 · 10<sup>12</sup> с<sup>−1</sup>.
