The oligomerization regularities of individual unsaturated components of pyrolysis liquid products / A. A. Lyapkov, A. V. Bondaletova, V. G. Bondaletov [et al.]
Уровень набора: Current trends in polymer scienceЯзык: английский.Страна: .Резюме или реферат: The relationship between the reactivity of the monomers and the electron density of the double ?-atom in the carbon-carbon double bond was determined. The density of the ?-atom can be estimated from the chemical shift of the respective protons shown in 1Н-NMR spectra. Correlation equations that allow us to determine the reactivity values of a range of vinyl monomers bearing electron-donating substituents under the influence of catalyst systems Et2AlCl–TiCl4 and TiCl4 are presented. The established relationships between reaction rate constants, enthalpy, polymerization activation energy and electron density of the ?-atom in the carbon-carbon double bond can be used to select the optimal duration and temperature for the synthesis of polymeric petroleum resins..Аудитория: .Тематика: электронный ресурс | труды учёных ТПУ Ресурсы он-лайн:Щелкните здесь для доступа в онлайнTitle screen
