STUDY ON LIQUID CRYSTAL POLYMERS WITH TWO-DIMENSIONAL MESOGENIC UNITS

A series of liquid crystalline polymers with two-dimensional mesogenic units were synthesized by solution polycondensation at low temperature. All the polymers were liquid crystalline. The melting temperature T_m (except that with substituent of methoxy) and the clearing temperature T_i of the polym...

Zusammenfassung:A series of liquid crystalline polymers with two-dimensional mesogenic units were synthesized by solution polycondensation at low temperature. All the polymers were liquid crystalline. The melting temperature T_m (except that with substituent of methoxy) and the clearing temperature T_i of the polymers change regularly with varying of the length of the alkyl substituent groups.
