A polymer is a substance of high molecular mass formed by the combination of very large number of repeating units. These repeating units are called monomers. The reaction by which a monomer is converted to a polymer is called polymerization. Polymers are of two kinds: Natural and synthetic.
Example of Monomer and Polymer
Examples of Natural polymers:
  • Starch, cellulose: monomer is glucose
  • Protein: monomer is amino acids
  • Natural rubber: monomer is isoprene
Examples of Synthetic polymers:
  • Polyethylene: monomer is ethylene
  • Poly vinylchloride¬†(PVC): Monomer is vinyl chloride
