Chain-growth polymerization
Videos
Chain-growth polymerization or chain-growth polymerisation is a polymerization technique where monomer molecules add onto the active site on a growing polymer chain one at a time. There are a limited
An example of chain transfer in styrene polymerization. Here X = Cl and Y = CCl3.
Step-growth polymerization

In polymer chemistry, step-growth polymerization is a type of polymerization mechanism in which bi-functional or multifunctional monomers react to form first dimers, then trimers, longer oligomers, an
Chain-growth polymerization
…of the reactive site(s) at the end of each growth step. (See Gold Book entry for note.) In 1953, Paul Flory first classified polymerization as "step-growth polymerization" and "chain-growth polymerization". IUPAC recommends to further simplify "chain-growth polymerization" to "chain polymerization". It is a kind of…
