J.720 ABSTRACT An absorbent material useful for immobilising blood consists of a blood-swellable, substantially water-insoluble, covalently cross-linked anionic polyelectrolyte having at least some of its anions associated with transition metal counterions which are capable of coagulating blood, the polyelectrolyte having the property that when the polyelectrolyte is contacted with blood transition metal counterions dissociate from the polyelectrolyte, diffuse into the blood and cause coagulation thereof.
