Aqueous Dispersion Terpolymerization of Acrylonirtrile, Acrylamide and Itaconic acid with Redox Initiator

Aqueous dispersion terpolymerization of acrylonitrile (AN), acrylamide (AAM) and itaconic acid (IA) was carried out in water at 40 °C using ammonium persulphate (APS) and sodium bisulfite (SBS) as initiators. Monomers composition in feed were 97.5/2/0.5 and 96.5/2.5/1 (AN/AAM/IA). The polymers were characterized by using Fourier transform infrared spectroscopy (FTIR), Differential scanning calorimetry (DSC). The dilute solution viscosities of these terpolymers were studied as a function of molecular weight. The incorporation of 2.5mol% AAM and 1mol% IA into terpolymer showed the better thermal behavior for carbon fiber producing
