PEGs show a spectrum of unique physical and chemical properties, which have been described in literature extensively by the pioneers in PEGylation: Harris, Veronese and recently by Hermanson. Here are summarized the most common known properties.
The polymers in this context are a polymeric linear structures with n repeating units of monomers. Depending whether the polymer is consisting of one single molecular weight (only one n existing) or of a range of compounds with an average mass and a distribution of n around a mean value, polymers are referred to as “monodisperse” or “polydisperse”.
