Conclusions
-
1.
The particular constants of chain transfer in the radical telomerization of ethylene and propylene by polychloromethanes were determined at pressures up to 8000 kg/cm2 and temperatures of 50 and 75°.
-
2.
The differences in the volumes of activation of reactions of substitution and addition of telomer radicals are practically insensitive to a change in the temperature; the differences in the enthalpy or entropy of activation in the range 1–8000 atm do not depend on the pressure.
