Polymer

A polymer is a large molecule made up of many smaller units called monomers linked together in a chain-like structure. These chains can be alone or form complex networks, giving polymers unique properties such as flexibility, strength, or elasticity. Common examples include plastics, DNA, and proteins. The way monomers connect and their chemical makeup determine a polymer's characteristics, making polymers versatile materials used in everyday products, medical devices, and countless industrial applications.
