In the present work, the binary polymer blends were prepared by mixing starch and chitosan in the 1:1 ratio with and without the cross linking agent like glutaraldehyde. The characterization of prepared polymeric blends was carried out by advanced analytical tools such as Fourier transform resonance spectroscopy (FT-IR), X-ray diffraction (XRD) and Thermo gravimetric analysis (TGA). The obtained results of FT-IR studies reveal the presence of cross linking between the polymers and cross linking agents. The results of TGA and DSC studies confirms that the blend prepared with glutaraldehyde as a cross linking agent was found to be highly thermally stable. In addition to this the results of water absorption studies carried out as a function of time for the polymer blend samples prepared with and without the cross linking agent at room temperature and high temperature was also investigated.
