In the present work, a novel random copolyester (P3BNI) based on 4,4’-biphenol,1,4-dihydroxy naphthalene with isophthaloyl chloride as different diols and diacid chloride monomers was synthesized by solution polycondensation method. Solubility was checked in common organic solvents. The Number average molecular weight (Mn) and Weight Average Molecular Weight (Mw) were obtained from a GPC thermogram. Qualitative structure analysis of the polymer was carried out by UV, FTIR and 1H NMR spectroscopy. The thermal analysis of copolyester was carried out by TGA and DSC studies. The thermal behavior of the copolyester was found to be very sensitive based on its chemical structure and thermal stability. The texture, morphology and crystallinity of the polyester were monitored using SEM and WAXD. The anti-proliferative effects of polyester was tested against HeLa cell line using MTT method. The results of the investigation reveal that the synthesized polymer was found to possess liquid crystalline nature and anticancer activity.
