Step-growth polymerization - Wikipedia

WebChain-growth polymerization can be split into three stages: initiation, propagation, and termination. Initiation involves producing an active center such as a free radical, ion, or polymer catalyst bond on a monomer molecule. Propagation is the simultaneous addition of monomer units and transfer of the active center to “grow” polymer chains.
