                Polymerization

                   Polymerization reactions are those reactions in which small molecules called as monomers join together to form a large molecule also known as polymers. These reactions are done via different mechanisms including addition reactions and condensation reactions.

              Proteins (polymer) are made up of amino acids (monomers) through condensation reaction as,

             n H₂N-RCH-COOH    →    H₂N-[-RCH]n-COOH  +  n H₂O

In above equation "n" represent large number, H₂N-RH-COOH represent amino acid (monomer) and H₂N-[-RH]n-COOH represent protein (polymer). While, the H₂O eliminated is the small neutral molecule.

               Other examples include Polystyrene, Polyethylene, Polyester, Teflon, DNA, Cellulose, Nylon e.t.c.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
