Solution

Assertion and reason both are correct statement but reason does not explain assertion.

Explanation:

In addition, polymerisation, the molecules of the same monomer of different monomers add together on a large scale to form a polymer. The monomers used are unsaturated compounds, e.g., alkenes, alkadienes and their derivatives. This mode of polymerisation leading to an increase in chain length or chain growth can take place through the formation of either free radicals or ionic species.
