Organic Chemistry - Polymerisation

Question

In the addition reaction of the polymer, Polystyrene, what is the initiation, propagation and termination stage?

Answer 1

Initiation reaction depends on the initiator that was used. That information is not provided. Propagation step is when a styrene with a single electron on it attacks another styrene molecule so you have a single electron formed on the other styrene. Termination step is when two polystyrene radicals meet and pair up to form a single bond.
