A process for the preparation of melt processable liquid crystalline terpolyesters by acetylating a monomer selected from 4-hydroxy phenyl acetic acid/3(4-hydroxyphenyl) propionic acid and hydroquinone/ 4,4'-biphenol/2,6-naphthalene with acetic anhydride in presence of a transesterification catalyst optionally in the presence of high temperature solvent followed by acidolysis polycondensation at a temperature in the range of 240-300°C for a period of about 6-24 hrs under reduced pressure for the efficient removal of acetic acid by soxhlet extraction using solvent mixtures selected from acetone-alcohol, acetone-methyl ethyl ketone to obtain melt processable liquid crystalline terpolyesters.
