1. What is a Polymer?

The term "polymer" originates from the Greek words "poly" (many) and "meros" (part). This linguistic structure defines the fundamental characteristic of polymers: materials composed of long molecular chains formed by repeating structural units. These repeating units are called monomers, constituting the basic building blocks of polymers. Polymers typically possess special properties due to their complex structures, allowing them to find extensive applications in industrial settings. The long molecular chains determine the physical and chemical properties of polymers. Additionally, polymers can be obtained from natural sources or synthesized synthetically in a laboratory setting. While naturally occurring polymers include cellulose and rubber, synthetic polymers encompass industrial products such as nylon, polyethylene, and polypropylene. This wide variety enables polymers to be used in different application areas. Polymer science continuously evolves to better understand and optimize the properties of these complex molecular structures. Consequently, polymer materials play a critical role in various industrial applications in engineering, medicine, chemistry, and other disciplines.
