WebPolymers are long chain macromolecules built from repeated smaller chemical structures or ‘ -mers .’ They are found widely in the natural world (e.g. proteins, rubber, cellulose) and, increasingly the past century, in synthetic form (e.g. “plastics”). WebApr 3, 2024 · Polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids. Moreover, they constitute the basis of such minerals as diamond, quartz, and feldspar and such man-made materials as concrete, glass, paper, plastics, and rubbers.
