Abstract—Highly water-absorbing polymers of neutralized poly(acrylic acid-co-MAA) onto Kappa-carrageenan were synthesized in an effort to investigate the influences of invironment parameters(pH, salinity) on water absorption. The polymerization reaction was carried out in an aqueous medium and in the presence of ammonium persulfate (APS) as an initiator. The structure of hydrogels were confirmed by FTIR spectroscopy Kappa-carrageenan and the hydrogels as well as solubility characteristics of the products.. In addition, the extent of water absorption and the absorption rate were studied to determine their relationship with the invironment parameters.
