Development of Rigid-Rod Liquid Crystalline Vinyl Polymer Based on Controlled Radical Polymerization

在这项研究中，我们重点研究了各种环状乙烯基单体的(受控)自由基(共聚)聚合，目的是基于它们的主链刚性来制备液晶乙烯基聚合物。我们进行了环状苯乙烯和烯烃衍生物的自由基(共)聚合，发现得到的(共)聚合物比传统的乙烯基聚合物具有更多的刚性骨架。其中，3，8-二甲基萘与N-环己基马来酰亚胺共聚物表现出溶致液晶性。

In this study, we focused our attention on(controlled) radical(co) polymerization of various cyclic vinyl monomers for the purpose of preparing liquid crystalline vinyl polymers based on their main-chain stiffness. We conducted radical(co) polymerization of cyclic styrene and olefin derivatives and found that the obtained(co) polymers possess more rigid backbone than the conventional vinyl polymers. Especially, 3, 8-dimethylacenaphthylene and N cyclohexylmaleimide based copolymer showed the lyotropic liquid crystallinity.
