Anionic polymerization mechanism
Accepted Answer
Anionic Polymerization Mechanism
Anionic polymerization is a type of polymerization that uses anionic initiators to start the polymerization process. Anionic initiators are typically strong bases, such as organolithium compounds or Grignard reagents. These initiators generate a nucleophile that attacks the monomer, forming a new carbanion. This carbanion then acts as a nucleophile to attack another monomer, and so on, propagating the polymer chain.
The anionic polymerization mechanism is a living polymerization, meaning that the polymer chains are not terminated and can continue to grow indefinitely. This allows for the synthesis of polymers with very high molecular weights.
Anionic polymerization is used to synthesize a variety of polymers, including polystyrene, polybutadiene, and polyisoprene. These polymers are used in a wide range of applications, including plastics, rubber, and adhesives.
