Аннотация

A thermogravimetric analysis of the thermal decomposition of polymethylmethacrylate (PMMA) in a carbon dioxide flow was carried out. 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 ⋅ 1016 to 6.85 ⋅ 1012 1/s. The average activation energy for the thermal decomposition of PMMA in a carbon dioxide flow was 206 kJ/mol.
