Water-retaining Agent of Zeolite/Carboxymethyl Cellulose Grafted Acrylamide

Using ammonium N,N-methylene-bisacrylamide and potassium sulfate as crosslinker and initiator respectively,a water retaining agent was prepared by graft polymerization of acrylamide on microcrystal cellulose in the presence of zeolite.The structure and interface of composites were characterized by FTIR.Parameters affecting water-adsorbing speed and water-retention capacity,such as the ratio of cellulose to monomer,the amount of zeolite,initiator and crosslinker,neutralization degree and the mass...
