Description

A polymer is a large molecule (macromolecule) composed of repeating structural units typically connected by covalent chemical bonds. Whereas the term polymer is sometimes taken to refer to plastics, it actually encompasses a large class of natural and synthetic materials with a wide variety of properties.
