Abstract:
The distribution of monomer concentration along the radius of a growing polymer particle is analysed for various polymerization times, and different values of the coefficients of diffusion and dimensions of the micro- and macroparticles of the catalyst, in the case of the polymerization of ethylene on highly active catalysts. A model for the growth of the polymer particle based on the results of electron microscopy is selected. It is shown that the diffusion of the monomer affects the rate of the process only during the initial stage of polymerization; with increase in yield the effect of diffusion is abrupty decreased. The probability of diffusional retardation of the process is determined only by the size of the catalyst particles and the porous structure of the polymer.
