Conclusions

The rate constants of the reaction between the alkyl radicals of hydrocarbons (R.) and of vinyl monomers (M.) and O2 and stable nitroxyl radicals
were determined at 50‡C. The low-molecular-weight radicals react with O2 (k1) and the
(k3) more rapidly than the M. do. For polar R. and M. k1 and k3 are close, and for the nonpolar ones k1>k3.
