Abstract
Abstract
The calculation of the main characteristics of the branching of the polymer is presented in the article using the example of polymerization of butadiene in the presence of an organolithium catalytic system modified with polyfunctional sodium and magnesium alcoholates. The addition of a modifier to the catalytic system leads to the participation in the polymerization of at least two types of active centers, which is the reason for some branching of macromolecules. The complemented mathematical model of the periodic process, taking into account the exchange of activity between the two centers, allows to calculate the main characteristics of branching.
