Abstract

Curing of mesogenic epoxy monomer p-Bis(2, 3-epoxypropoxy)-cz-methylstilbene (DOMS) with aromatic amines is discussed. The crosslinking density is controlled using a mixture of biand tetra-functional hardener. The unidirectional alignment of the molecules was achieved during the curing process by external factors such as surface-liquid crystal interactions.
