One of the most famous silicon-based polymers is SilIy Putty. Molecular Arrangement of Polymers Think of how spaghetti noodles look on a plate. This is similar to how polymers can be arranged if they lack a specific for or are amorphous. Controlling and quenching the polymerization process can result in amorphous organization. An amorphous arrangement of molecules has no long-range order or form in which the polymer chains arrange themselves.
Amorphous polymers are generally transparent.
This is an important characteristic for many applications such as food wrap, plastic windows, headlights, and contact lenses. Obviously not all polymers are transparent. The polymer chains in objects that are translucent and opaque are in a crystalline arrangement. By definition a crystalline arrangement has atoms, ions, or in this case, molecules in a distinct pattern. You generally think of crystalline structures in salt and gemstones, but not in plastics.
