摘要
A series of thermotropic liquid crystalline copolyesters were synthesized by thermal polycondensation of p-hydroxybenzoic acid, terephthalic acid, bis (4-hydroxyphenyl )methanone and diols. The resulting copolyesters were characterized by WAXD, DSC and PLM.All the copolyesters formed a nematic phase.
