The synthesis and the mesomorphic properties of liquid crystalline polymer
networks and the linear polymers upon which networks are based are reported
. The linear polymers, synthesised from trimellitic acid, 2-allyl ester wit
h the appropriate 4,4'-l,n diphenoxyalkane, exhibit a nematic mesophase, as
indicated by calorimetric analysis, X-ray diffraction data, and polarising
microscopy. Polymer networks were prepared from the linear polymers in the
anisotropic state by thermal crosslinking in the bulk producing a very sta
ble liquid crystalline phase.
