含二羟基二苯酮热致液晶共聚酯的合成与表征（Ⅵ）──含二羟基二苯酮热致液晶共聚酯结晶结构的X射线衍射研究

Synthesis and Characterization of Thermotropic Liquid Crystalline Copolyesters Containing Bis(4-hydroxyphenyl)Methanone Series──Ⅵ.WAXD Study on thermotropic Liquid Crystalline Copolyesters Containing Bis(4-hydroxyphenyl) Methanone

以广角Ｘ－射线衍射（ＷＡＸＤ）对含二羟基二苯酮（ＢＨＰ）、对羟基苯甲酸（ＰＨＢＡ）、对苯二甲酸（ＴＰＡ）、问苯二酚（ＲＥＳ）的系列热致液品共聚酯进行了较为深入的研究，详细讨论了不同组成的共聚酯的结晶结构、结晶度、结晶颗粒大小等等。

In this paper, WAXD was used to investigate the structure of liquid crystalline copolyesters based onbis(4-hydroxyphenyl) methanone, terephthalic acid, p-hydroxybenzoic acid and resorcinol. Degree ofcrystallinity, crystal structure and crystal size of different component copolyesters were studied.
