Title: Advances of high water-absorbent starch graft copolymers
Abstract: The research progress and production of high water-absorbent starch graft copolymers were elaborated by means of two preparation methods, i. e. chemical initiation and radiation initiation. The research status quo was introduced for the high water-absorbent resins of starch grafting acrylonitrile, starch grafting acrylic acid and starch grafting multi-monomers and complex type starch graft copolymers that were made by way of chemical initiation, and major factors were reviewed including starch density,monomer density, initiator, cross-linker and neutralization degree. The advantage and the application of the technique were discussed for high water-absorbent starch graft copolymers that were made by way of radiation initiation including microwave radiation initiate, ultraviolet light radiation initiate and 7 ray initiate. Some new trends in their development such as multi-monomers grafting on starch, preparation of complex and anti-salt supper-absorbent resins, microwave solid synthesis, simple process,efficient initiator and reinforcing basic theory study were pointed out.
