Abstract:

The present study deals with the synthesis and characterization of the ternary blends of carboxymethyl cellulose, polyethylene glycol and montmorillonite clay of ratio 1:1:1 in the presence and the absence of the crosslinker glutaraldehyde. The prepared blends were characterized using the analytical tools such as FTIR, TGA, DSC, XRD and SEM. The effective formation of the ternary blend was confirmed using FTIR studies. The thermal stability of the blends was determined from the TGA and DSC results. XRD and SEM results confirm that the degree of crystallinity was altered during blending and crosslinking and the prepared blend is suitable for adsorption and also as an excipient material in pharmaceutical industries.
