Synthesis of Novel Polysaccharide-Based Superabsorbent Hydro Gels Via Graft Copolymerization of Vinylic Monomers onto Kappa-Carrageenan

Mohammad Sadeghi and Fatemeh Soleimani

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.

Index Terms—Kappa-Carrageenan Meth Acrylic Acid,Acrylic Acid, Water Absorption
