Ionic polymerization

IUPAC definition

Chain polymerization in which active centers are ions or ion pairs.

Note 1: Usually the chain-ends are ions, although ions can also be located

on the monomer molecules, as in an activated-monomer polymerization.

Note 2: The ions may also be present in the form of higher aggregates

that usually are less reactive than non-aggregated species.

Modified from the earlier definition.[1]

Ionic polymerization is a chain-growth polymerization in which active centers are ions or ion pairs.[2] It can be considered as an alternative to radical polymerization, and may refer to anionic polymerization or cationic polymerization.[3]
