由具有刚性介晶结构同时又具有双键的单体进行加聚反应,是制备侧链型液晶高分子最方便的方法。大多采用甲基丙烯酸酯或丙烯酸酯类,聚合后形成乙烯型柔性主链,同时侧链上又带有刚性介晶相结构单元。以联苯类作为介晶相的液晶,由于具有稳定性好的优点,是目前应用得最广泛的一种液晶材料。Maganini用自由基聚合的方法进行了侧链型联苯液晶高分子的合成和研究。基团转移聚合作为一种新的加聚方式,为丙
It is the most convenient method to prepare side-chain liquid crystal polymer by polyaddition reaction of monomer with rigid mesogenic structure and double bond. Most of the use of methacrylates or acrylates, ethylene polymerization to form a flexible main chain, while the side chain with a rigid mesophase structure unit. Biphenyl as the mesophase liquid crystal, due to the advantages of good stability, is currently the most widely used as a liquid crystal material. Maganini by free radical polymerization method of side chain biphenyl liquid crystal polymer synthesis and research. Group transfer polymerization as a new method of polyaddition, as C
