dc.description.abstractThe work is devoted to synthesis of new triazolinyl stable radical derivatives with different substituents at the 5-position of the triazolinyl ring. Obtained results showed great influence of these substituents on the stability of the radical. Electron-rich aromatic substituents at this position stabilize the radical while electron-poor aromatics decrease the stability of the triazolinyl. The triazolinyl radicals synthesized were used as additives for kinetic investigations of controlled radical polymerization of styrene and methylmethacrylate (MMA). The studies performed showed that the more stable radicals provide better control for the polymerization of styrene. In the same time certain instability of the radical is required for realization of controlled polymerization of methylmethacrylate. Based on the kinetic investigations controlled radical polymerization of a variety of monomers including 4-vinylpyridine (4-VP), ethylmethacrylate (EMA), 2,2,2- trifluoroethylmethacrylate (FEMA) and n-butylmethacrylate (BMA)was successfully carried out. Polystyrene and polymethylmethacrylate macroinitiators prepared by triazolinyl mediated controlled radical polymerization were efficiently reinitiated in the presence of a variety of monomers leading to the formation of block copolymers. Using this method PS-b-P-4-VP, PMMA-b-PS, PMMA-b-PBMA, PMMA-b-PFEMA, and PMMA-b-Poly-tert-butylacrylate were successfully synthesized. The results obtained during this work showed the efficiency and flexibility of the method allowing preparation of a range of advanced macromolecular structures.en_GB
