摘要： 将修饰的β-环糊精衍生物单-(6-丙烯酰乙二氨基-6-去氧)-β-环糊精二十乙酸酯(M1)作为手性单体,4-十一烯酰氧基苯甲酰氧基-4’-乙氧基苯甲酰氧基对联苯酚双酯(M2)作为液晶单体,与聚甲基含氢硅氧烷接枝共聚,得到含β-环糊精基元的液晶聚合物P1～P7.通过FT-IR,1H NMR,DSC,POM,TGA,XRD,旋光分析等手段对所获单体及聚合物的结构、相行为等性能进行了表征与测试.结果表明,单体M1为非液晶手性单体,其比旋光度为+95.30,单体M2呈现向列相的丝状织构,聚合物P1～P7均有液晶性,它们的热稳定性良好,热失重5%时的温度均在300℃左右,随着手性单体M1含量的增加,聚合...

Abstract: With the chiral monomer mono-(6-acryl ethylenediamino-6-deoxy)-β-cyclodextrin twenty acetate(M1) and liquid crystal monomer 4-[(p-undecylen-1-yloxy) benzoyloxy]-4'-(p-ethoxy) benzoyloxy biphenyl ester(M2) both grafted onto the backbone of polymethylhydrosiloxane, a new kind of liquid crystalline polymers P1~P7 containing β-cyclodextrin was prepared. Their structures and properties were characterized with FT-IR, 1HNMR, DSC, POM, TG, X-ray and SROT. The results showed that M1 is a chiral non-mesogenic monomer whose optical rotation is +95.30 and M2 presents a threaded texture of the nematic phase, while P1~P7 are thermotropic liquid crystalline polymers with high thermal stability and 5% heat loss about 300°C. With increasing M1 content in the polymers, the liquid crystal phase is shortened and specific opticity is increased.
