WebRing-opening polymerization is a reaction in which one polymer chain has a reactive center on its terminal end that reacts with another cyclic monomer, hence opening its ring system to form a longer polymer chain. The reactive center on the terminal end of the polymer chain can be ionic, cationic, or radical.
