Реферат:
A mathematical model of the polymerization process is suggested on the basis of kinetic data, obtained for the polymerization of ethylene with supported titanium-magnesium catalysts of various compositions differing in particle size, content of electron donor modifier, oxidation state of titanium in the initial catalyst and combination with different cocatalysts. The model includes stages of the formation and deactivation of active sites and
takes into account monomer diffusion into the polymer particle. The analysis of experimental data by means of the mathematical model allowed to obtain the rate constants for single stages of the polymerization process. The suggested model and the obtained set of parameters allow to make a satisfactory description of a wide spectrum of experimental data, corresponding to different shapes of kinetic curves. The kinetic parameters were found to depend on the oxidation state of titanium in the catalyst and on the nature of the cocatalyst.
