Polymers are substances whose molecules have high molar masses and are composed of a large number of repeating units. There are both naturally occurring and synthetic polymers. Among naturally occurring polymers are proteins, starches, cellulose, and latex.
Monomers are the basic molecular form in which polymers and plastics are produced. Polymers consist of repeating molecular units, which usually are joined by covalent bonds. For a molecule to be a monomer, it must be at least bifunctional insofar as it has the capacity to interlink with other monomer molecules.
