Polymerization reaction consists of initiation, propagation, and termination steps.

• Initiation step involves the formation of free radicals or ions that start the reaction.

• Propagation step involves the growth of the polymer chain by the addition of monomers.

• Termination step involves the end of the reaction, either by the consumption of all monomers or by the combination of two polymer chains.

• Polymerization reactions can be classified as addition polymerization or condensation ...read more
