By providing chain initiation, benzoyl peroxide functions as an initiator in free radical addition polymerisation of alkenes.
The generated radical reacts with the carbon-carbon double bond of an alkene molecule to produce a polymer.
The new free radical combines with a monomer’s double bond to produce a bigger free radical, which then combines with another alkene molecule to form the polymer.
