摘要
本文揭示了液晶共聚酯的红外光谱、直接裂解质谱、裂解气相色谱、核磁共振谱和凝胶渗透色谱的主要特征，并讨论了它们的大分子链组成、序列结构和分子量分布，同时给出了其链结构分布的普适规律。
The major features of infrared,direct pyrolysis-mass spectra,pyrolysis gas chromatography,nuclear magnetic resonance and gel permeation chromatography of the liquid crystalline copolyester were revealed in detail.Their chain composition,sequence distribution and molecular weight distribution were discussed.A general rule for the 'chain structural analysis was also given.
