Resumo
The theoretical regularities of the physical modification of the TiCl4–Al(i-C4H9)3 catalytic system (dispersion of the particles of its catalytically active residue) in eddy flows created in a tubular eddy apparatus of diffuser confuser design were determined. The change in the particle size of the catalytically active residue of the TiCl4–Al(i-C4H9)3 catalytic system as a result of growth of macromolecules during the ion-coordination polymerization of butadiene (“wedging” effect) was described in terms of the probability theory. The relationships (at 298 K) between the activities of the growth centers of macromolecules in the TiCl4–Al(i-C4H9)3 catalytic system physically modified in eddy flows and not physically modified and the equivalent radius of the particles of its catalytically active residue were represented as functional dependences.
