Beschreibung
Zusammenfassung:	The present invention relates to a process for the preparation of a hydrogel suitable as carrier in a hydrogel-linked prodrug, to hydrogels obtainable from said process, the use of such hydrogel as a carrier in a hydrogel-linked prodrug and to hydrogel-linked prodrugs comprising a covalently conjugated hydrogel of the present invention. The hydrogel prodrug carrier has a reduced drug loading on the outside of the hydrogel carrier. This is achieved by reducing the number of functional groups of the hydrogel, in particular those at its surface.
