The reason the anion on the product side of the reaction in Equation 26-12 is more stable than the anion on the reactant side is to be explained. Concept introduction: Beside the free-radical mechanism, chain-growth polymerizations can also be initiated by anions or cations, resulting in anionic polymerization or cationic polymerization respectively. For example, styrene can undergo anionic polymerization using butyllithium as the initiator, which forms a negative charge on the growing chain instead of an unpaired electron (Equation 26-12).

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
