Abstract:
     The method is provided for preparing the polymer having high absorptivity of water by directly saponifying, cross-linking and dissociating reaction to polyacrylonitrile without graffing onto other polymer matrix with aluminium sulfate [AL2(SO4)3.18H2O]or potassium aluminium sulfate [kAL(SO4)2.12H2O].the product has a distillated water absorbing capacity of 400-800times as large as it's own weight.
