A chemical reaction in which two or more small molecules combine to form larger molecules that contain repeating structural units of the original molecules. A hazardous polymerization is the above reaction with an uncontrolled release of energy.

Polymerization is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains [1]. There are many forms of polymerization and different systems exist to categorize them.

The main categories are

Polymerization dates back to the beginning of DNA based life, as both DNA and proteins can be considered polymers. The first 'synthetic' polymers of the 19th century were actually formed by modifying natural polymers. For example nitrocellulose was manufactured by reacting cellulose with nitric acid. The first genuinely man-made polymer, the phenol-formaldehyde resin bakelite, was synthesized in 1872. However, research into polymers and polymerization only really accelerated in the 1930s after the serendipitous discovery of polyethene by the chemical company ICI.

–noun Chemistry
1. the act or process of forming a polymer or polymeric compound.
2. the combination of many like or unlike molecules to form a more complex product of higher molecular weight, with elimination of water, alcohol, or the like (condensation polymerization), or without such elimination (addition polymerization).
3. the conversion of one compound into another by such a process.

In a very rough translation (Please correct the spelling if you actualy know it) .
'Poly' from the Greek = 'Many '.
'Mer' from the Greek = 'sea'(or Carbon).
'Mono' from the Greek ='single'.
Hence Monomer meaning single 'Sea' Or 'C' Carbon atom.
Polymer many C's.
To Polymerise is to join carbon based monomers together.
To go further than this would be involved as there are a multitude of polimerisations reactions.
