It is shown that, in the case of the peroxide initiator, ferrocene derivatives form highly efficient initiation systems, which make it possible to polymerize methyl methacrylate at a high rate, to reduce the molecular mass of polymers, and to synthesize polymers with a high content of syndiotactic triads, while in the case of AIBN, such systems are not formed. \\\\Cserver\\Dist\\НБО\\Электронная библиотека_Библиогр1\\Polymer science.

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): CYCLIC PEROXIDES -- POLYMERIZATION -- THERMAL DECOMPOSITION Аннотация: Cyclic peroxides as initiators for the radical polymerization of methyl methacrylate were proposed. The initial rates, initiation rates, and effective activation energies of polymerization initiated by cyclic peroxides and cyclic peroxide-1-pyridyl-2-ferrocene systems were determined. The radical yields to the volume upon the thermal decomposition of cyclic peroxides and their catalytic decomposition in the presence of 1-pyridyl-2-ferrocene were determined. In combination with 1-pyridyl-2-ferrocene cyclic peroxides form efficient initiating systems favoring an increase in the polymerization rate, a decrease in the molecular weights, and an increase in syndiotacticity of the synthesized poly(methyl methacrylate). \\\\expert2\\nbo\\Russian Chemical Bulletin\\2013, 62 (5), 1282-1285.pdf |

A sensitive, direct, and easily measured analytical response is obtained by cyclic voltammetry. The developed method enables the determination of bacterial cells at a minimum concentration of 2.3 x 10(3) CFU/mL. The analytical range is 2.3 x 10(3)-2.3 x 10(7) CFU/mL; the detection limit is 2.5 x 10(2) CFU/mL. The required sample volume is 0.5 mL, and the analysis time is 40 min. \\\\expert2\\nbo\\Journal of Analytical Chemistry\\2015, V. 70, N 5, p.540-545.pdf |
