Abstract:
The results of mathematical modeling of the catalytic polymerization of ethylene, performed within the framework of a multiparticle model, showed that morphology of the final polyethylene (PE) particles may be significantly affected by in homogeneity of the initial active component distribution in the catalyst particles. It was found that, in contrast to the existing notions according to which the catalyst particle structure uniquely determines the final structure of polymer grains, the local changes in concentration of the active component may lead to the appearance of b01h loose (voids) and dense regions in the local polymer structure. It was also established that retarded internal diffusion of the monomer may lead to a decrease in density of the internal regions of PE grains and, eventually, in the polymer powder density.
