Sodium alginate prepared from alginic acid was then graft copolymerized with acrylic acid monomer using hydrogen peroxide(H2O2) as an initiator, and the grafted copolymer was identified by IR spectroscopy method. When the amounts of sodium alginate, acrylic acid and hydrogen peroxide was kept constant in the reaction medium and then the contents of emulsifier was varied, SA conversion showed the maximum at the 3.0g of emulsifier and above that value it showed the downward trend. In the aqueous sodium alginate solution when the amounts of acrylic acid, hydrogen peroxide and emulsifier was remained constant and then the contents of sodium alginate was varied, AA conversion showed the maximum at the 15.0g of sodium alginate and above that value it showed the downward trend.
