摘要：
The liquid crystalline polyacrylamides (PAAD-R) having secondary or tertiary amide groups were synthesized and the thermal properties of PAAD-R were studied. PAAD-H with the secondary amide group exhibited enantiotropically smectic phases with enhanced thermal stability through the formation of hydrogen bonding between amide groups when compared to PAAD-M with the tertiary amide group. Also, a liquid crystalline polyacrylate, which has the same mesogenic side chain as PAAD-H, was prepared and the thermal properties of PAAD-H and PA were compared.
