Question

What is the role of benzoyl peroxide in polymerisation of ethene?

Answer 1

Acts as a chain initiator by breaking and then forms into 2 benzyl chloride free radicals and then involves itself in chain propagation

Answer 2

Hey dear,

● Role of benzoyl peroxide in ethene polymerization -
- Polymerization of ethene is by free-radical polymerization.
- It involves 3 steps - initiation, propagation & termination.
- Free radical required here for chain initiation.
- Benzoyl peroxide decomposes to form free radicals.
(C6H5-COO)2 ---> 2C6H5-COO•

* Peroxide here can be just considered as catalyst.
