摘要
本文讨论了既氧间隔基对聚硅氧烷液晶行为的影响，它比对应的含烷氧间隔基聚合物多了向列相，并给出了十一烯－［１０］酰氧苯甲酸－４－个甲氧基苯酯及合同一个晶基元侧链聚硅氧烷的变温ｘ－射线衍射曲线、热谱图和焓、熵热力学数据．单体呈现向列相纹影织构，均聚物显示向列相微滴状和Ｓｃ相破碎扇形织构，聚合后相态数增加．
The effect of undecyloyloxy spacer on the liquid crystalline behavior of side-chain polyxiloxane was discussed. WAXD and DSC curves, entropy and enthalpy of benzony-4-methoxyphenyl undecyle-[10]-nate and side-chain polysiloxane containing 4-methoxyphenyl benzoate mesogens were given. Nematic thread-schlieren texture for monomer and nematic droplet and smectic C broken fan-shaped texture of polysiloxane were observed.
