| Abstract: | The melting behavior and crystal structure of thermotropic liquid crystalline copolyesters, which were synthesized by melt polycondensation from bis(4-hydroxyphenyl) methanone, terephthalic acid, p-hydroxybenzoic acid and aliphatic diols, were investigated. The results proved that there existed two crystal forms in the crystal structure of these copolyesters, which showed two endotherms on the DSC curves. Furthermore, degree of crystallinity and crystal size of these copolyesters were studied. |
