Figure 3.12 Molecular structure of several linear polymers. All but the last two are related
to the polyethylene structure by simple substitutions, R, R 1 and R 2 ,or F.
Figure 3.13 Crystal structure of polyethylene. Layers similar to that shown in the diagram
are seen edge-on in the photo, being arranged in a radiating pattern to form the
prominent crystalline features called spherulites. (Photo courtesy of A. S. Holik,
