摘要： 由于胆甾型高分子液晶具有特殊的螺旋结构,很小的外界能量就能使其结构排列发生变化,对热、光、电、磁等有非常灵敏的响应,作为功能材料有着广泛的应用前景。本文以甲基丙烯酸羟丙酯(HPMA)为单体,通过2,4-甲苯二异氰酸酯(TDI)与胆甾醇接枝,合成了带胆甾侧基的聚甲基丙烯酸羟丙酯共聚物。核磁与红外分析证明了该聚合物的结构。

Abstract: By reacting 2, 4-di-isocyanatotoluene with cholesterol and 1, 2-hydroxypropyl methacry-late, a new monomer containing cholesteric group was prepared. The monomer was then copolymerized with 1,2-hydroxypropyl methacrylate in different proportions. Copolymers with cholesteric ester side chain from 1,2-hydroxypropyl 2,4-diisocyanatotoluene methacrylate were prepared.The formation of monomer and copolymer has been identified by IR and NMR spectroscopic methods.
