Calculation of relative rate constants of radical addition to vinyl monomers by means of proposed empirical scheme. When possible, values calculated from experimental data [ 1 ] shown.

The following abbreviations are used:
vinyl monomers: MSt, α-methylstyrene; MAN, methacrylic nitryl; MMA, methyl methacrylate; IPA, isopropenylacetate; VBuE, vinyl buthyl ether; ViPy, vinylpyridine; MVK, methylvinylketone; DPE, 1,1-diphenylethene; VF, vinyl fluoride.
Radicals: poly-Xxx polyalkyl radicals ∼CH2−C^•HY, generated from vinyl monomers in polymerization.
