POROUS ABSORBENT MATERIALS HAVING MODIFIED SURFACE CHARACTERISTICS AND METHODS FOR MAKING THE SAME

摘要

A porous absorbent material that comprises a water-insoluble, absorbent poly mer. The absorbent material comprises a polyether and or a polycation bonded to the absorbent polymer whereby the contact angle of blood on a surface of the absorbent mat erial attains from about 0 degree to about 40 degrees. Because of the improved wet tability with liquids as well as the porous structure, t he absorbent material can provide higher absorbent characteristics with liquids , in particular with blood.
