| 摘要 |
Modified polysaccharides having greatly increased water-absorbing and binding capacity are prepared by reacting a polysaccharide such as cellulose or starch in the presence of acrylamide, another vinyl monomer and a divinyl crosslinking monomer using free radical polymerization techniques. The product is believed to be a complex mixture of crosslinked grafted polysaccharide and acrylamide copolymers. |
