A Study on Synthesis and Structure of Side Chain Liquid Crystalline Polyacrylates Containing Para-Nitro Azobenzene 1. Synthesis of Side Chain Liquid Crystalline Polyacrylates Containing Para-Nitro Azobenzene

摘要: 设计合成了溴烷基(对硝基偶氮苯基)醚■和含硝基偶氮苯的丙烯酸酯■两组化合物;用自由基聚合和化学改性两种方法合成了含硝基偶氮苯侧基的丙烯酸酯液晶聚合物,用DSC,偏光显微镜和x-射线衍射等方法表征了聚合物的相行为。

Abstract: Two series of compounds containing para-nitro azobenzene as mesogen were synthesized. The side chain liquid crystalline polymers containing para-nitro azobenzene were prepared by free radical polymerization and chemical modification of poly (acrylic acid)
