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