  • Title: Graft copolymerization of ethylacrylate onto xanthan gum, using potassium peroxydisulfate as an initiator.
    Author: Pandey S, Mishra SB.
    Journal: Int J Biol Macromol; 2011 Nov 01; 49(4):527-35. PubMed ID: 21693131.
    Abstract:
    Graft copolymer of xanthan gum (XG) and ethylacrylate (EA) has been synthesized by free radical polymerization using potassium peroxydisulfate (KPS) as an initiator in an air atmosphere. The grafting parameters, i.e. grafting ratio and efficiency decrease with increase in concentration of xanthan gum from 0.050 mg/25 mL to 0.350 mg/25 mL, but these grafting parameters increase with increase in concentration of ethylacrylate from 9×10(-2) to 17×10(-2) ML(-1), and KPS from 15×10(-3) to 35×10(-3) ML(-1). The graft copolymer has been characterized by FTIR, XRD, TGA and SEM analysis. The grafted copolymer was also evaluated as efficient Zn(2+) metal binder. The grafted copolymer shows improvement in the stability, solubility as well as their sorbing capacity. Thus graft copolymer formed could find applications in metal ion removal and in drug delivery.
