Status: current

Definition
Anionic polymerization in which a cyclic monomer yields a monomeric unit that is either acyclic or contains fewer rings than the cyclic monomer.

Example
Intramolecular anhydrides of N-carboxy amino acids (commonly referred to as N-carboxy anhydrides or NCAs), epoxides and cyclic siloxanes.
