Abstract

Ternary polymer blends were prepared by mixing of carboxymethyl cellulose, polyvinyl alcohol (PVA) and glass fibre in the various ratios. The characterization of various polymeric blends were carried out by advanced analytical techniques such as Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and Thermo gravimetric analysis (TGA). The changes in the degree of crystallinity of the prepared blend were elucidated from X-ray diffraction studies. From the TGA studies, it was evident that the prepared carboxymethyl cellulose /polyvinylalcohol/glass fibre has highly thermally stable behavior and the results were investigated.

Keywords: Carboxymethyl cellulose, polyvinyl alcohol, glass fibre, ternary blend.
