Preparation of Copolymer Modified with Oxidized Starch and Dispersion Ability for Ferric Oxide

Abstract:

A series of copolymers modified with oxidized starch containing maleic anhydride (MA), styrene sulfonic sodium (SSS) and oxidized starch (OS) were synthesized by the free-radical polymerization. The polymerization is initiated by ammonium persulfate. The effects of content of monomer and initiator, reaction time, reaction temperature on dispersion ability for Fe₂O₃ were investigated by single factor experiment. The dispersion ability for Fe₂O₃ measured through UV spectroscopy was studied. The experimental results show that the copolymer has good dispersion ability for Fe₂O₃ when the mass proportion of monomers is OS:SSS:MA = 1:3:1, the mass fraction of initiator in total monomers is 10 %, reaction time is 5 h, and the reaction temperature is 70 ^oC. The morphology of the copolymer was observed by scanning electron microscope (SEM). The experimental results indicate that the prepared copolymer modified with oxidized starch could be used in the corrosion inhibitor of high temperature water.
