    • a values of 9-10. At pH 7, most of the amines are thus protonated. It is reasonable to assume that most of the amines of the denpols investigated in this study behave as independent, primary amines and thus, are also protonated. The degree of protonation was not determined. The counterion in all cases was trifluoroacetate.

    • The molar mass was determined by performing gel permeation chromatography (GPC) with a polystyrene standard. This probably underestimates the actual molar mass.

    • Even when the NMR spectra of deprotected samples with very high signal-to-noise ratios were amplified considerably, there was no indication that deprotection was incomplete.

    • note
    • The term ultrastructure was coined by microscopists and describes the level of organize that is below the level of resolution of the light microscope. In practice, it is a shorthand term for structure observed by using the electron microscope.
