Unlike free-radical polymerisation, purely anionic polymerisation systems (conducted in highly purif — Polymers Chemistry Question

💡 Solution & Explanation

In purely anionic polymerizations without impurities (like water, oxygen, or acids), the growing chain ends are carbanions which repel each other, preventing termination by combination. Unless a quenching agent is added, the active centers remain indefinitely, forming what are known as "living polymers."
