摘要：

The solid-state morphology of poly(hexamethylene p,p prime -bibenzoate) (BB-6) and its dependence on the liquid-crystalline texture was studied by transmission electron microscopy. Thin films of BB-6 were prepared by casting a solution of the polymer in tetrabromoethane onto mica at 150 degree C. The temperature of the thin film was controlled on a hot-plate. The thin, liquid-crystalline films (210 degree C) which formed from the isotropic melt (260 degree C) were cooled gradually to room temperature. Long, plate-like structures composed of stacked lamellar crystals were formed in a thin film prepared from the thermotropic melt. An attempt was made to explain such a morphology in terms of Dupan's cyclide by assuming that a hyperbola in the cyclide is parallel to the surface of the BB-6 film. (Edited author abstact)
