Kinetic of radical telomerization of acrylic acid in the presence of 1-octadecanethiol / Y. O. Mezhuev, О. Y. Sizova, Y. V. Korshak et al. // Pure and Applied Chemistry. — 2018. — Vol. 90, no. 11. — P. 1743–1754. The oligomer of acrylic acid with a thiooctadecyl end-group was obtained by using octadecyl mercaptan as the chain-transfer agent. The resulting oligomer was characterized by 1H NMR and 13C NMR spectroscopy and critical micelle concentration was determined in aqueous solution. The order with respect to the initiator concentration was 0.5 and 1.6 with respect to the monomer concentration. The abnormal reaction order with respect to the monomer concentration was explained by participation in the chain propagation of unassociated and associated forms of acrylic acid, which were stabilized by formation of hydrogen bonds. The kinetic parameters of telomerization were determined. Telomerization with acrylic acid in the non-associated form had lower activation energy and lower pre-exponential factor than in the case of associated forms. The synthesis of the acrylic acid oligomer with a thiooctadecyl end-group having a low critical micelle concentration in water was carried out in one stage and corresponds to the concept of atom economy.

Synthesis of amphiphilic oligomers of acrylic acid / Y. O. Mezhuev, O. Y. Sizova, A. L. Luss et al. // Russian Journal of General Chemistry. — 2018. — Vol. 88, no. 10. — P. 2139–2143. Synthesis of amphiphilic oligomers of acrylic acid via radical polymerization in the presence of thiols as molecular mass regulators is described. The effect of the length of the introduced hydrophobic terminal group on the critical micellization concentration of the acrylic acid oligomers has been elucidated. It has been shown that the incorporation of an antituberculous drug (prothionamide) in the micelles of acrylic acid oligomers is enhanced with the increase in the length of the hydrophobic moiety. The preparation of hydroxyapatite-filled calcium-polycarboxylate bone cements containing prothionamide (promising for the sealing of postoperative cavities) is described. [ DOI ]
