Small molecular weight crosslinking agents containing hydrolyzable bonds were photopolymerized with poly(ethylene oxide) in order to decrease the pore size of the gels. The resulting cogels decreased in equilibrium swelling volume (pore size) as the concentration of crosslinker increased. The initial release profile of the model protein albumin showed a decreased burst in the presence of small molecular weight crosslinkers in the photopolymerized hydrogels.
