Cure kinetics of liquid crystalline epoxy resins based on biphenyl mesogen [PDF]

, 2014
The cure kinetics of a biphenyl-based liquid crystalline (LC) epoxy resin (LCER) was studied using differential scanning calorimetry (DSC) and polarized optical microscopy. The effects of LC phase formation on the cure kinetics were investigated.
