Mathematical modeling of the continuous process of butadiene polymerization over a neodymium-based catalyst with allowance for its polycentric nature and chain transfer to the polymer in a cascade of stirred reactors

Abstract

A mathematical model for continuous butadiene polymerization under the effect of a neodymium versatate-diisobutylaluminum hydride-hexachloro-p-xylene catalytic system is developed that takes into account its polycentric nature and chain transfer to the polymer in a cascade of stirred reactors. The constructed mathematical model adequately describes industrial data and makes it possible to calculate not only the average molecular weights, but also the characteristics of polymer branching at the outlet of the kth reactor of the cascade.
