Addition Polymerization
It is a reaction that forms a polymer compound while a double bond of a monomer forms a new single bond.
When the monomers are bonded, no other small molecules are produced other than the polymer.
It is a reaction that occurs mainly when making plastics in the modern chemical industry.
