Abstract
A process of preparing a biodegradable single-phase cohesive hydrogel composition includes preparing 2 to 5 hydrogels that are independently crosslinked so that each hydrogel has a degree of crosslinking in a range from 0.02 to 0.4, and mixing the 2 to 5 hydrogels to obtain a homogenous mixture of 2 to 5 intertwined hydrogels that interpenetrate each other to form a single phase without covalent bonding between the hydrogels, wherein each hydrogel is prepared by a process that comprises independently crosslinking a polymer and the total polymer concentration of the composition is in a range from 5 to 50 mg/g.
