crucial roles in biological processes. A variety of other natural polymers exist, such as cellulose, which is the main constituent of wood and paper. The list of synthetic polymers includes Bakelite, neoprene, nylon, PVC, polystyrene, polyacrylonitrile, PVB, silicone, and many more. Polymers are studied in the fields of polymer chemistry, polymer physics, and polymer science. Starting in 1811, Henri Braconnot did pioneering work in derivative cellulose compounds, perhaps the earliest ...

If we replace the hydrogens with fluorines, we get PTFE which you know by the trade name Teflon. Polypropylene. Polystyrene which you have seen in these clamshells. Not so much today in coffee cups for their insulating capability. Polyacrylonitrile is a fabric Orlon. PVC is that white tubing that you see used in plumbing facilities. Polymethylmethacrylate, many of you are wearing eyeglasses that are made of this material. This is Plexiglas or Lucite. And so on. And down here even some of ...
