Figure 28. (a) Inset. Electron diffraction pattern obtained from the central region of a collapsed bowl-shaped crystal of P4MP formed on cooling polymer solution to 50 °C. The arms of the cross drawn at the center of the pattern point to the strong 200 reflections, (b) Selected region from which the diffraction pattern was obtained. The arms of the cross drawn at the right hand side of the micrograph indicate the preferred orientation of the {100} microfacets in the terraces situated in the central portion of the crystal. Gold shadowed, × 7500.
