| Özet |
| A series of fully aromatic copolyesters based on p‐acetoxybenzoic acid (p‐ABA), hydroquinone diacetate (HQDA), terephthalic acid (TPA), and m‐acetoxybenzoic acid (m‐ABA) were prepared by a modified melt‐polycondensation reaction. The copolyesters were prepared in two series in which series I is based on a two monomer system (p‐ABA/m‐ABA) and series II is based on a three monomer system (HQDA/TPA/m‐ABA). The effect of different linear structures and kink moiety on the properties of the copolyesters were investigated systematically. The copolyesters were characterized by differential scanning calorimetry, thermogravimetric analysis, 1H‐NMR, polarized optical microscopy, X‐ray diffraction, and intrinsic viscosity measurements. It was found that the copolyesters exhibited nematic liquid‐crystalline phases when the content of linear (p‐ABA or HQDA/TPA) units was over 67 mol %. The melting or flow … |
