Summary Terephthalate copolyesters containing ethylene glycol and either tetramethylene, TMG, or hexamethylene, HMG, glycol and p-oxybenzoate, OB, units were investigated by DSC and IR spectroscopy for the relationship between composition and thermal transitions. Copolymers containing more than 30 mole% OB units showed melt birefringence indicative of thermotropic liquid crystalline behaviour. The IR results were applied quantitatively by plotting optical densities as a function of temperature over the melting range of the copolyesters.
