本论文的主要内容分为两部分：第一部分，针对目前液晶材料研究的热点：含氟液晶和环己烷类液晶，就其液晶材料中间体氟代苯酚和烷基环己基苯类化合物的合成进行研究。

Their thermotropic phase behavior was investigated by differential scanning calorimetry and POM. It was found that T(subscript S-N) w and T(subscript N-I), of PMMAZO was slightly increased with the increased of the mass ratio of liquid crystal block segments. PEO and PMMA block affected the liquid cystal behavior of PMMAZO. Meanwhile, PMMA and PMMAZO obviously influenced the crystals property of PEO segments3 which was decreased as the increase of molecular weight of PMMA and PMMAZO segments.

以差示扫描量热仪和偏光显徽镜研究了ABC三嵌段共聚物PEO-b-PMMA-b-PMMAZO的热力学相转变行为，发现随着PMMAZO链段的质量百分比的增加，三嵌段共聚物中PMMAZO链段的T和T逐渐提高；同时，PMMA和PMMAZO链段的长短影响PEO链段的结晶性，随着液晶段PMMAZO和PMMA链段分子量的增加，PEO链段的结晶性减弱。
