Novel random photocrosslinkable copolyesters with Oxygen Bridge were prepared from4; 4’- oxybis and1, 6-hexanediol with 1, 8-dihydroxyanthroquinone/1, 4-cyclohexanediol/4, 4’- dihydroxydiphenyl by direct polycondensation in pyridine/LiCl solution (DPCP) was employed as the condensation agent. The glass transition temperature of these polymers was determined by differential scanning calorimetry (DSC). Spectral studies such as 1H, 13C NMR and FTIR gave an insight about the microstructure and monomer composition. Resulting polyesters were blended with polyvinylchloride (PVC)/ tetrahydrofuran (THF) in 10% (w/w) ratio.Nanofibers obtained by electrospinning process were subjected to UV irradiation to investigate on the photocrosslinkability by observing the changes in morphology of the fibers by scanning electron microscopy(SEM). The photocrosslinkability of these polymer solutions was established with UV irradiation / UV spectroscopy. These polyesters and their blend nanofibers could be used in photolithographic devices and photosensitizers.
