Chain propagation
<templatestyles src="Template:Quote_box/styles.css" />
Chemical reaction between a chain carrier and a monomer
that results in the growth of a polymer chain and
the regeneration of at least one chain carrier.
Note 1: The recommended symbol for the rate constant for
chain propagation in a homopolymerization is kp.

Chain propagation (sometimes referred to as propagation) is a process in which a reactive intermediate is continuously regenerated during the course of a chemical reaction. In a polymerization reaction, the reactive end-groups of a polymer chain react in each propagation step with a new monomer molecule transferring the reactive group to that last unit.
