Abstract: With crylic salts,zeolite,agar etc as raw materials,super-absorbent composite were prepared by water solution cross-linked polymerization.The factors such as the ratio of agar to monomer,the amount of initiator and crosslinker,the amount of zeolite added and neutralization degree were also discussed.Water retention of composite materials was explored.The structure was characterized by IR.The results showed that zeolite was well dispersed in the composite.The resin can absorb 596（g/g）pure water a...
