Answer: Polymer molecules, or macromolecules, are composed of large numbers of linked, small repeat units. The units from which polymers are synthesized are called monomers.
Polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds.
