Which of the following vinyl monomers is most susceptible to anionic polymerization initiated by str — Polymers Chemistry Question

💡 Solution & Explanation

Anionic polymerization is highly selective and favorable for monomers containing strong electron-withdrawing groups, which stabilize the intermediate carbanion. The cyano group ($-CN$) in acrylonitrile is strongly electron-withdrawing, making it highly susceptible to anionic initiation.
