    Abstract: Homogeneous hydrogels comprise a water-soluble sugar, derivative or mixture thereof, radiation cross-linked with at least one ethylenically unsaturated compound. A preferred combination is sucrose or glucose cross-linked with acrylic acid. The hydrogels may contain additives e.g. plasticizers such as glycerol. The hydrogels are strong and expand to a large extent e.g. 30.times. on water absorption. They are particularly suitable for use in medical dressings, preferably bonded to a supporting film which may be a semi-permeable membrane allowing control of water loss. A method for preparing such a hydrogel and dressing is also described.
