通过开环复分解聚合制备了一系列具有聚降冰片烯主链和不同侧基的介晶包覆液晶聚合物（MJLCP）。通过差示扫描量热法、偏光显微镜和广角 X 射线衍射研究了这些聚合物的液晶 (LC) 相行为。根据刚性侧链核心和外围烷基链的不同，这些聚合物表现出不同的液晶结构。具有三联苯刚性侧链核和相对较短烷基尾部的聚合物在整个温度范围内是无定形的，而具有相同刚性侧链核但较长烷基尾部的聚合物呈现柱状向列相（Coln）。具有较长刚性侧链核心和相对较长烷基尾部的聚合物发展成近晶A (SmA) 相。此外，本研究中获得的液晶聚合物在较宽的温度范围内显示出液晶相。
A new series of mesogen-jacketed liquid crystalline polymers (MJLCPs) with a polynorbornene main chain and different side groups were prepared by ring-opening metathesis polymerization. The liquid crystalline (LC) phase behaviors of these polymers were investigated by differential scanning calorimetry, polarized light microscopy, and wide-angle X-ray diffraction. Depending on the rigid side-chain core and peripheral alkyl chains, these polymers show different LC structures. The polymer with the terphenyl rigid side-chain core and relatively short alkyl tails is amorphous in the whole temperature range, while those with the same rigid side-chain core but longer alkyl tails exhibit columnar nematic (Coln) phases. Polymers with a longer rigid side-chain core and relatively long alkyl tails develop into smectic A (SmA) phases. In addition, the LC polymers obtained in this study display LC phases in wide temperature ranges.
