    Notes: Abstract The concept of the apparent electronegativity of a reaction site has been introduced. This has been used to develop a new scheme for calculating the relative rate constants of addition of radicals with different structures to vinyl monomers. The parameters of the scheme are given for 40 reagents. The results of a comparison of calculated and literature rate constants of addition are presented.

    Rate constants for addition of phenoxyl radicals to the vinyl monomer double bond (1992)
    Springer
    Russian chemical bulletin 41 (1992), S. 2147-2151 
    Details
    ISSN: 1573-9171
    Keywords: vinyl monomers ; radical oxidation ; inhibitors ; phenols ; reactivity ; kinetics

    Notes: Abstract Rate constants were measured for the addition of the 2,4,6-tri(tert-butyl)phenoxyl radical (logk 10, [liter/(mole · sec)]) to the double bond of styrene (9.73 − 4621/T), methyl methacrylate (10.1 − 4972.7/T) and butylacrylate (7.68 − 4313.9/T); and for addition of the 2,4,6-tribromophenoxyl radical to styrene (k 10=0.5;T=323 K). A simulation based on these constants for the inhibited oxidation of styrene under conditions similar to those of monomer storage demonstrated the need to take account of this reaction when analyzing kinetic schemes describing the inhibited oxidation process.
