Abstract
The thermal decomposition of the polypropylene and liquid paraffin mixtures with inorganic additives was studied in dynamic conditions. Thus, typical thermal analyses were carried out and thermal decomposition of samples in a specially designed apparatus was also processed. One can observe for samples of sufficiently low mass that thermal analysis allows clear distinction of samples that contain and do not contain liquid paraffin, respectively. Moreover, it is possible to separate two stages of the decomposition process. The relationship between the logarithm of conversion degree and temperature (so called three-parameter model) was used for the description of these processes. Relations between coefficients in three-parameter equation in micro-scale, and characteristic temperatures of thermal decomposition in laboratory scale were observed in spite of meaningful differences in the course of the processes.
