摘要: | 本研究之主要目的是合成柔軟間距6,9,10,12個次甲基單位,四系列含旋 光基的側鏈液晶聚合物,此四系列環氧丙烷化合物,都以 Bontrifluoride ethercomplex作為起始劑,進行開環聚合,合成出以環 氧丙烷為高分子主鏈之新型側鏈液晶聚合物。 Presenting the synthesis and characterization of side- chain liquid crystalline polyoxetanes containing chiral group is the goal of this study. Four series of polymers contain the same polyoxetane backbone and 6,9,10 or 12 methylene groups spacers. The prepared oxetane monomers were polymerized by a ring- opening polymerizatinon using BF3.OET2 as a initiator. The obtained monomers and polymers are characterized by DSC, Optical polarizing microscope (OM) and X-ray diffraction. |
