Abstract
A glycidyl-terminated liquid crytalline (LC) monomer is cured with aro matic amines. A nematic structure suddenly develops during the curing reaction and is related to the molecular weight increase of the develo ping network. An unusual exothermal double peak is observed in the iso thermal curves obtained in a defined temperature range. The calorimetr ic analysis is used to evaluate the kinetic parameters and is related to the initial formation of a linear prepolymer and to the subsequent development of the tridimensional network.
