Volume : I, Issue : VII, August - 2011 INVESTIGATION ON NOVEL LIQUID CRYSTALLINE COPOLYESTERS FROM 2-HYDROXYETHYL- 4-HYDROXYBENZOATE S.VASANTHI, J. ARUL MOLI, D. ROOP SINGH DOI : 10.9780/22307850, Published By : Laxmi Book Publication Abstract : A novel series of liquid crystalline random copolyesters with different
mesogenic units were synthesized using diphenylchlorophosphate as a
condensing agent in pyridine. The structural features of these polymers were
studied using FT-IR and 1H NMR spectral data. The thermal behaviour of
these polymers was studied by DSC technique. A study on glass transition
temperatures of the polymers in correlation with different monomer and
mesogenic units was carried out. Enigmatically, these polyesters were found to
possess liquid crystallinity and hence they may be potential candidates for
device technology. Keywords : Article : Cite This Article : S.VASANTHI, J. ARUL MOLI, D. ROOP SINGH, (2011).
