ABSTRACT:
A selected powdery form of a graft copolymer containing hydrophilic chains provides a highly moisture-absorbent media which is suitable for use in absorbent bodies, particularly those used for absorbing body exudates such as catamenial devices, diapers, wound dressings, surgical sponges, incontinence pads and the like. The powdered form of said copolymers is useful alone or in combination with other absorbent materials in making up the absorbent bodies.
