polymer

     

A polymer is a large molecule (macromolecule) compose of repeating structural units connected by covalent chemical bonds. The word is derived from the Greek, πολυ, poly, "many"; and μέρος, meros, "part". Well known examples of polymers include plastics, DNA and proteins. A simple example is polypropylene whose repeating unit structure is shown at right.

Trivia about polymer

  • A substance, like a plastic, made of macromolecules; the American Chemical Society has a division of this "chemistry"
  • (Sarah of the Clue Crew inserts a needle into a balloon.) The balloon doesn't break because it's made up of this type of substance, from the Greek for "many parts"; the needle merely separates the large molecules
