Graft copolymerization of acrylate or methacrylate monomers onto sodium alginate by APS-TU initiation was studied. The copolymer structure was characterized by IR and X-ray diffrac-tion, Maximum G%and E%were obtained at[APS]=[TU]=(6-8)10￣(-3)mol/L,[M]=0. 6mol/L,SA=2.0g/100ml,60℃ for 4h.The reactivity order of monomer was:MMAGMAMAEMA.
