Question

Draw a mechanism showing the linkage of three styrene monomers to make the polymer. What is the expected regiochemistry and why?

Answer 1

Answer #1

Poly styrene is formed by the polymerization of monomer of styrene that is vinyl benzene.

It is free radical addition mechanism, the initiator is benzoyl peroxide

The mechanism is as follows

The regioselectivity is doubled bond of styrene. This is because styrene has unsaturated double bonds. So free radical attacks at the double bond.
