Eight-armed PEG was functionalized with furyl and maleimide groups (8armPEG20k-Fur and 8armPEG20k-Mal); degradable hydrogels were obtained by cross-linking via Diels-Alder chemistry. To increase the stability to degradation, the macromonomers were modified by introducing a hydrophobic 6-aminohexanoic acid spacer between PEG
