In the present work, graft co-polymerization of acrylonitrile (AN) onto Saccharum cilliare fibre has been carried out in the presence of potassium persulphate and ferrous ammonium sulphate (FAS-KPS) as redox initiator. The reactions were carried out under pressure in an autoclave. Various reaction parameters such as pressure, time, pH, concentrations of initiator and monomer were optimized to get maximum graft yield (35⋅59%). Grafted and ungrafted Saccharum cilliare fibres were then subjected to evaluation of some of their properties like swelling behaviour in different solvents, moisture absorbance under different humidity levels, water uptake and resistance towards chemicals such as hydrochloric acid and sodium hydroxide. The characterization of the graft copolymers were carried out by FTIR spectrophotometer, X-ray diffraction (XRD) and scanning electron microscopic (SEM) studies.

This article deals with the study of graft copolymerization of methylmethacrylate (MMA) onto Saccharum ciliare fiber in air in the presence of ferrous ammonium sulfate-potassium persulfate (FAS-KPS) as redox initiator. After optimizing the various reaction parameters such as solvent, time, temperature, concentration of monomer, and initiator to obtain maximum graft yield (58%), the grafted fiber has been characterized by various techniques such as scanning electron microscopy (SEM), Fourier transform-infrared spectrophotometry (FT-IR), X-ray diffraction, and thermogravimetric=differential thermal analysis along with DTG studies. The raw fiber and graft copolymerized fibers were also subjected to evaluation of different physical and chemical properties.

The present paper deals with the graft copolymerization of acrylonitrile (AN) onto Saccharum cilliare fiber in air in the presence of ferrous ammonium sulfate - potassium persulphate (FAS - KPS) as redox initiator. Various reaction parameters such as solvent, time, temperature, pH and concentration of monomer and initiator were optimized in order to get maximum graft yield (69 %). Raw fiber and its graft copolymers with AN were then subjected for evaluation of different properties. Characterization of the graft copolymers was carried out with Scanning electron microscope, Fourier transform infrared spectrophotometer and X-ray diffraction studies (X-RD).
