Abstract

AbstractThe use of loomstate cotton fabric (starch sized fabric) as a substrate for grafting of methacrylic acid using KMnO4/citric acid as initiator provided an effective method with greater potentiality. Presence of starch size on the fabric helps the deposition of MnO2 over the fabric with subsequent acceleration of the grafting reaction. Major factors affecting polymerization of MAA, such as KMnO4, citric acid and MAA concentrations, as well as reaction time and temperature of polymerization were studied. A tentative mechanism for the polymerization reaction is suggested.
