Abstract
By using a polymer containing a dichloroethylene structure derived from a vinylidene chloride monomer in the molecule in place of an unsaturated polyester and an urethane resin, there can be obtained an excellent adsorbent which has improved workability in case of granulation and high strength, and causes little deterioration of its ion exchange capacity even after a large number of regenerations.
