Evaluation of Structure-Controlled Polysiloxane Functoionality Materials

1.通过固体核磁共振弛豫性能的研究，建立了结构与渗透性能之间的关系。将所建立的原理应用于开发可用于角膜接触镜的材料.在液晶高分子的分子设计中，充分利用了硅氧烷键的特性。发现了一类新型的含硅氧烷间隔基和介晶基团的聚丁二烯液晶高分子.聚氧杂环丁烷与氰基联苯或氟联苯被发现是一类新的液晶聚合物。从阴离子聚合的观点来看，氟取代基特别令人感兴趣。该尾基将使得可以通过阴离子聚合获得液晶聚合物的良好控制的结构（macromolecules，Polym. Bull.）。4.合成了苯基上带有烷氧基或烷基取代基的甲基丙烯酸三苯基甲酯。通过自由基、阴离子和不对称选择性阴离子聚合获得聚合物（Polym. J.）。

1. Relationship between structure and permeation property was established by studying the relaxation property by solid state NMR. The established principle was applied to develop materials which can be used for contact lens.2. Characteristic property of siloxane linkage was taken advantage in molecular designing liquid crystalline polymers. Polybutadiene with siloxane spacer and mesogenic groups was found as a new class of liquid crystalline polymers.3. Polyoxetanes with cyanobiphenyl or fluorobiphenyl were found to be liquid crystalline polymers of new class. Specially fluorine substituents are interested from the view point of anionic polymerization. This tail group will make it possible to obtain well controlled structure of liquid crystalline polymers by anionic polymerization (macromolecules, Polym. Bull.).4. Triphenylmethyl methacrylate having alkoxy, or alkyl substituent on one of the phenyl groups were synthesized. Polymers were obtained by radical, anionic, and asymmetric selective anionic polymerizations (Polym. J.).
