Curable mixtures of mesogenic epoxy resins and mesogenic polyamines and cured compositions

摘要

Compositions comprising epoxy resins containing one or more rodlike mesogenic moieties per molecule are cured with polyamines containing one or more rodlike mesogenic moieties per molecule. These curable compositions can be oriented by the application of an electric field or magnetic field or drawing and/or shear flow prior to and/or during curing. The resultant cured products exhibit an improvement in one or more physical and/or mechanical and/or thermal properties as compared to a like epoxy resin system which does not contain any rodlike mesogenic moieties.
