Hierarchical Structures in a Main-Chain/Side-Chain Combined Liquid Crystalline Polymer with a Polynorbornene Backbone and Multi-Benzene Side-Chain Mesogens Ping-Ping Hou, Zhen-Yu Zhang, Qian Wang, Meng-Yao Zhang, Zhihao Shen, and Xing-He Fan Macromolecules 2016, 49(19), 7238-7245. |
A series of main-chain/side-chain combined liquid crystalline polymers (MCSCLCPs) with a polynorbornene backbone and multi-benzene mesogens in the side chain, PNbnPP (n = 2, 6, 10), were synthesized through a controllable polymerization method: ring-opening metathesis polymerization (ROMP).

transfer agent and atom transfer radical polymerization. The glass transition temperature (Tg) of the PMPCS hard block is 110?118 °C in the triblock copolymers. In addition, the liquid crystalline (LC) phase of PMPCS is stable before thermal decomposition. All the triblock copolymers form lamellar microphase-separated structures, as demonstrated by small-angle X-ray scattering and transmission electron microscopy results. The triblock copolymer (M-B-M-55) with a mass fraction of 55% of PMPCS exhibits typical properties of an LC thermoplastic elastomer (LCTPE). The maximum elongation at break and the tensile strength of M-B-M-55 are 736% and 10.6 MPa, respectively, and the stretching strength at 300% is 6.9 MPa. Above the Tg of PMPCS, the LC phase of PMPCS provides new physical cross-linking points in the LCTPEs, and the triblock copolymer M-B-M-55 still shows a relatively high modulus. |
Effects of rigid cores and flexible tails on the phase behaviors of polynorbornene-based mesogen-jacketed liquid crystalline polymer Zhen-Yu Zhang, Qian Wang, Ping-Ping Hou, Zhihao Shen and Xing-He Fan Polymer Chemistry 2015, 6(44), 7701-7710. |
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.
