Chemically modified jute fiber (Tossa variety) has been grafted onto 2-ethyl hexylacrylate (2-ERA) to prepare copolymer using in situ developed transition metal complex initiating system; CuSO4/glycine/potassium monopersulfate (KMPS). Then its composites have been prepared by incorporating montmorillonite (MMT) clay. The samples have been characterized by Fourier Transform-Infrared (FTIR) spectroscopy and surface morphology by Scanning Electron Microscopy (SEM). The thermal behavior and tensile strength of the samples have been studied. The fire retardant properties are studied using oxygen consumption cone calorimeter. The biodegradability of the composites has been tested to see if it is ecofriendly by nature and viable for better commercialization.
