Reversible-deactivation polymerization in which the kinetic-chain carriers are anions.
Examples: - Group-transfer polymerization of methyl methacrylate initiated by 1-methoxy-2-methyl-1-(trimethylsiloxy)prop-1-ene (traditional name is methyl trimethylsilyl dimethylketene acetal) and catalysed by a nucleophile.
- Anionic polymerization with reversible formation of an ion-pair or a different ion cluster size.
