Early medical devices were based on high purity grades of commonly used industrial A polymer is a large molecule, or macromolecule, composed of many repeated subunits. Due to their broad range of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural "Ask the Historian: The origin of the polymer concept" (PDF). What are Polymers?
