Synthesis and Molecular Mechanics Calculation of Copolyesters

Copolyesters and polyesters are similar as both have carboxylate ester in the repeating copolymers of a diol and diacid. In the present work, copolyesters based on adipoyl chloride with aromatic and aliphatic diols were synthesized by solution polycondensation method. To ascertain the quality of the synthesized copolyester materials, a satisfactory vibrational band assignments has been made for some of the specific modes of vibration observed from FTIR spectra. The assignments are very well supported by Laser Raman spectral studies and molecular mechanics calculations.
