Summary

The hydrogen bonding of liquid crystalline epoxy resin with aromatic ester mesogenic group was investigated using FT-IR. The hydrogen bonding in the hydroxyl and carbonyl region was described. Free hydroxyl, intermolecular hydrogen bonding and intramolecular hydrogen bonding was observed in the cured LCE/DDS system. The amount of free hydroxyl was proportional to the content of curing agent and intramolecular hydrogen bonding showed adverse tendency with the content of curing agent. Carbonyl region was analyzed by curve fitting and the amount of hydrogen bonded carbonyl increased with the curing time and the content of curing agent.
