Several polymers were synthesized by reaction of unsymmetrical diacids with 4,4′‐bis(2,3‐epoxypropoxy)biphenyl. The reaction progress was followed, and the structure of the polyesters obtained was evaluated by means of 13C NMR spectroscopy. It appeared to be possible to achieve control in the polymer structure as a function of reactivity of the diacids. To obtain unequivocal assignments and to characterize thoroughly the NMR spectra of the polymers, several model compounds resembling the polymer backbone were synthesized.
