The exact value of the apparent Cs for methyl acrylate cannot be quoted with certainty as the extent of Co-C bonding will affect the equilibrium Co(II) concentration, which as a result will be dependent on the radical concentration and (at the initial stages) the conversion. The Cs range of 10-20 quoted in the paper is the result of one experiment and should only be seen as a general indication of the magnitude of Cs for the chain transfer reaction of COBF with methyl acrylate.
