The formation of micelles from a surfactant and the addition of a molecule such as potassium persulfate initiate the emulsion variety of this process, while the formation and propagation of oxonium ion centers characterizes the cationic variant of the ring-opening (*) type of this process.  
One way of carrying out this procedure is the "sacrificial spacer" approach, which employs a fixed template that is removed after this procedure is complete. The formation of micelles from a surfactant and the addition of a molecule such as potassium persulfate initiate the emulsion variety of this process, while the formation and propagation of oxonium ion centers characterizes the cationic variant of the ring-opening (*) type of this process.  Another mechanism of this process follows the "principle of least nuclear motion," and results in a regeneration of a vacant site with a configuration opposite from the original vacancy; that mechanism is named after Cossee and Arlman. Stereoselectively produced by catalysis with Ziegler-Natta complexes, for 10 points, identify this procedure of forming large molecules from identical units.
