摘要: Epoxy resins containing more than one vicinal epoxide group per molecule and at least one thiadiazole, oxadiazole or both thiadiazole and oxadiazole moiety per molecule are disclosed, as well as curable and cured compositions thereof. Certain of these epoxy resins possess enantiotropic liquid crystallinity. These enantiotropic epoxy resins are useful in preparing copolymers with high glass transition temperatures and liquid crystalline morphology, which can result in enhanced unidirectional mechanical properties. These epoxy resins are useful in coating, casting, encapsulation, electronic or structural laminate or composite, filament winding or molding applications.

摘要: Novel polycyanate compositions containing one or more mesogenic moieties as lateral substituents are disclosed which provide improved processability relative to polycyanates containing one or more mesogenic moieties in the main chain of the molecule. Molecular level ordering of the resulting thermosets is maintained much similar to that found thermosets of polycyanates which have one or more mesogenic moieties in the main chain.
