Abstract

Abstract The results of studying the kinetics of the polyisoprene synthesis in the presence of neodymium-containing catalytic systems under conditions of preliminary hydrodynamic action at the stage of preparation of the catalytic complex are reported. Mathematical research methods allow expansion of the results of laboratory studies to the scale of continuous industrial production and evaluating the effect of dosages of triisobutylaluminum and diisobutylaluminum hydride on the molecular characteristics of the resulting product. The essential role of triisobutylaluminum, which is initially present in the composition of the catalytic complex, has been demonstrated in the mechanism of limiting the growth of polymer chains.
