    • This approximate relation has been obtained by growing chains simultaneously in bulk and on the surface and determining M via size exclusion chromatography and h via ellipsometry. Although it has been found to be valid for a range of methacrylates and acrylates grown from BMPUS initiator layers deposited under identical conditions, this relationship should be considered as an estimate only because it assumes that chains grown under confinement possess the same rate of polymerization as those polymerized in solution. Nevertheless, this relationship provides a very reasonable estimate for the chain grafting density σ, σ ≈ 0.45 chains/nm2
