Abstract

A copolyester was synthesized using 2,5-Ditertarybutrylquinol as one of the diols with isophthaloyl chloride as an Acidchloride. In addition, 1,4-Butanediol, have also been used as another comonomer for the synthesis of random copolymer. Formation of copolyester have been confirmed using various spectral techniques viz., Ultraviolet (UV), Fourier Transform Spectroscopy Infrared (FTIR), Nuclear Magnetic Resonance (NMR) spectral techniques. Thermal studies were also carried out using Differential Scanning Calorimetry (DSC) and Thermo Gravimetric Analysis (TGA). Elemental analysis further supports the formations for the copolymer. Morphology of the copolyester has also been characterized using Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) Method. Results of the investigation reveals that a relatively new entry of copolymer has been suggested into the family of liquid crystalline copolymers.
