Abstract
An absorbent material that comprises a water-insoluble, water-swellable absorbent polymer. The absorbent material comprises a reactive polyether chemically bonded to the absorbent polymer whereby the contact angle of blood on a surface of the absorbent material attains from about 0 degree to about 40 degree. Because of the improved wettability with liquids, the absorbent material can provide higher absorbent characteristics with liquids, in particular with blood.
