1.The constants of chain transfer of radicals with n=1–3 in the telomerization of vinyl chloride with chloroform at 55, 90, 115, and 135° were determined within a broad range of reagent ratios.2.All the constants of transfer were two orders of magnitude lower than in the telomerization of CHCl3 with ethylene or propylene, but were more sensitive to the temperature; the particular constants change negligibly with increasing n.3.In the consideration of the mechanism of the telomerization of vinyl chloride with CHCl3, the Bumford correlation scheme was used to estimate the polarity of the reagent and the possible contribution of polar structures to the transition states of reactions of substitution. |
