Abstract:
Disclosed herein is a hydrogel wound dressing produced by the steps of a) providing an hydrophobic polyol which has six hydroxyl groups, b) providing an hydrophilic diisocyanate obtained by reacting a second diisocyanate with a hydrophilic polyether diol, c) reacting the hydrophobic polyol with the hydrophilic diisocyanate to obtain a first prepolymer which includes 3 to 6 isocyanate groups, d) partially crosslinking the first prepolymer using a crosslinking agent to obtain a second prepolymer, and e) subjecting the second prepolymer to an end-capping reaction with a silane-containing compound to obtain the hydrogel wound dressing.
