Organic polymers are large molecules (or macromolecules) composed of many repeating subunits called monomers. Both natural and synthetic polymers play a crucial role in everyday life. Polysaccharides, polypeptides, and polynucleotides are the main types of biopolymers in living cells. In general, synthetic polymers are derived from monomers that contain either a multiple bond, two or more functional groups, or a three- to seven- membered ring. The chemical properties of polymers are derived from their monomer units, while the physical properties of polymers, such as toughness, elasticity, and viscoelasticity, are different. Depending on their physical properties, polymers are characterized as thermoplastics, thermo sets, elastomers, and fibers.
