Abstract: X-ray diffraction patterns of natural, formaldehyde crosslinked and cyanoethylated cotton samples graft copolymerized with methyl, ethyl, n-butyl acrylate and methyl metthacrylate monomers have been studied. The prominent equatorial and meridional reflection arcs of native cotton remained unaffected as a result of modification by cyanoethylation, crosslinking and grafting, but the intensity of the diffuse background scattering was increased slightly. The Bragg angles and the corresponding interplanar spacing’s, d101 and d002, for natural cotton cellulose also did not change indicating that no transformation of unit cell has taken place. The crystallite size was not affected, whereas crystallite orientation was decreased due to chemical modification and grafting.
