Anionic polymerization

英语百科

Anionic addition polymerization

Initiation through strong anion.
IUPAC definition for anionic polymerization

Ionic polymerization in which the active centers are anions.

Note 1: The anions may be free, paired, or aggregated.

Modified from the earlier definition.

Anionic addition polymerization is a form of chain-growth polymerization or addition polymerization that involves the polymerization of vinyl monomers with strong electronegative groups. This polymerization is carried out through a carbanion active species. Like all chain-growth polymerizations, it takes place in three steps: chain initiation, chain propagation, and chain termination. Living polymerizations, which lack a formal termination pathway, occur in many anionic addition polymerizations. The advantage of living anionic addition polymerizations is that they allow for the control of structure and composition.
