Nanocarriers are a platform for modern drug delivery. In contact with blood, proteins adsorb to nanocarriers, altering their behavior in vivo. To reduce unspecific protein adsorption and unspecific cellular uptake, nanocarriers are modified with hydrophilic polymers like poly(ethylene glycol) (PEG). However, with PEG the attachment of further functional structures such as targeting units is limited...
The authors introduce poly(ethylene glycol) (PEG) based macromonomers containing acid‐labile ketal moieties as well as terminal methacrylate units that are amenable to radical polymerization. The synthesis of PEGs of different molecular weights (ranging from 2000 to 13 000 g mol−1 with polydispersities <1.15) with a central ketal unit (PEG‐ketal‐diol) and their conversion to PEG‐ketal‐dimethacrylates...
