Abstract
Novel catalytic systems based on complexes of copper(II) bromide with polydentate nitrogen-containing ligands, tris[(2-pyridyl)methyl]amine and tris[(2-dimethylamino)ethyl]amine, and salts of organic acids (Rochelle salt, sodium oxalate, sodium lactate, and sodium pyruvate) acting as catalyst regenerating agents have been developed for the radical polymerization of acrylonitrile. It has been shown that the polymerization of acrylonitrile carried out in the presence of these systems and halogen-containing initiators occurs by the atom transfer mechanism, affording polymers with target molecular weight values. Effect of the nature of reducing agent and initiator on the process of polymerization and the degree of control over molecular weight characteristics of the resulting samples has been studied. It has been found that Rochelle salt and sodium oxalate are the most efficient reducing agents allowing for a high rate of polymerization while maintaining control over the process.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
