通过三步反应合成了阳离子有机硅表面活性剂聚（甲基（γ-（2-羟基-3-N，N-二甲基-N-苄基氯化铵））-丙基）硅氧烷（QAMPS），聚（甲基氢）硅氧烷（PMHS）与烯丙基缩水甘油醚（AGE）的硅氢化反应，与二乙胺的加成反应和与苄氯的季铵化...通过三步反应合成了阳离子有机硅表面活性剂聚（甲基（γ-（2-羟基-3-N，N-二甲基-N-苄基氯化铵））-丙基）硅氧烷（QAMPS），聚（甲基氢）硅氧烷（PMHS）与烯丙基缩水甘油醚（AGE）的硅氢化反应，与二乙胺的加成反应和与苄氯的季铵化反应。通过1 H NMR、IR对其化学结构进行了表征，结果表明QAMPS的每个重复单元均含一个季铵阳离子。通过DSC和表面张力仪QAMPS的性质进行了研究，结果表明QAMPS具有较低的玻璃化转变温度（Tg）和临界胶束浓度（CMC）。展开更多
Two liquid crystal monomers,cholesteryl 10\|undecylenate (M1), and cholesteryl 4\|(10\|undecylenoyloxy)\|benzoate(M2),and their respective side\|chain liquid crystal homopolymers (P1,P2) were synthesized.Their liquid ...Two liquid crystal monomers,cholesteryl 10\|undecylenate (M1), and cholesteryl 4\|(10\|undecylenoyloxy)\|benzoate(M2),and their respective side\|chain liquid crystal homopolymers (P1,P2) were synthesized.Their liquid crystal properties were characterized by POM and DSC method.M1 could form sematic liquid crystal and cholesteric liquid crystal,while M2\|only cholesteric liquid crystal.The Polymers,P1 and P2,exhibited sematic liquid crystal behavior.The results also indicated that,because of the structure of 1,4\|COO\|Ar\|COO\|in M2 and P2,the isotropization tempretures of the liquid crystalline M2 and P2 were higher than those of M1 and P1,respectively,and the temprature range of LC phases of M2 was also wider than that of M1.Homopolymer P1,was applied in the capillary column gas chromatography as a novel stationary phase and showed ideal separating selectivity.A mixture of anthracene,phenanthrene and acenaphene and a mixture of dichlorobenzene isomers were well separated.展开更多
