采用对氯苯甲醛和联苯二胺为原料,合成了4,4′-二氯代苄叉联苯胺,发现该化合物具有热致液晶性。利用所合成的二氯代化合物与硫化钠在醋酸锂催化下缩取得得到了含硫聚西佛碱探讨了高分子量含硫聚西佛碱的合成方法。测出该含硫聚西佛碱具有3.4×10~(-11)S/cm本征导电率。使用红外光谱、元素分析等方法表征了所合成的聚合物。
Using p-chlorobenzaldehyde and biphenylenediamine as raw materials, 4,4’-dichlorobenzylidenebenzidine was synthesized and found to have thermotropic liquid crystallinity. The synthesized dichloro compound and sodium sulfide were clamped under the catalysis of lithium acetate to obtain the sulfated polysilicone. The synthesis method of the high molecular weight sulfur-containing polysilicone was discussed. The Sulphuric Sulfur containing sulfur was found to have an intrinsic conductivity of 3.4 × 10 ~ (-11) S / cm. The synthesized polymers were characterized by IR, elemental analysis and other methods.
