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