Polymerase Chain Reaction - Dr. Kary Banks Mullis
The ion produced in this reaction adds monomers to produce agrowing polymer chain.
Polymerase Chain Reaction Making DNA accessible
'Polymerase Chain Reaction' is now a word in Merriam Webster's Collegiate Dictionary and if you put 'PCR' into Google, you get 18,000,000 hits. If you type in 'pcr song,' you get a lovely little ditty courtesy of Bio-Rad, which will rattle around in your brain like an insane cat in your garage. Try it.
He thought I should have called it "in vitro cloning." I liked "Polymerase Chain Reaction.. The discipline of paleobiology would certainly not care to part with it now, under any name.
Synthesis Reactions (Description and Examples) - …
When the chain reaction is initiated and carried by negativelycharged intermediates, the reaction is known as anionicpolymerization. Like, these chain reactions take place viachain-initiation, chain-propagation, and chain-termination steps.
The intermediate that carries the chain reaction duringpolymerization can also be a positive ion, or cation. In thiscase, the cationic polymerization reaction isinitiated by adding a strong acid to an alkene to form acarbocation.

The simplest way to catalyze the polymerization reaction thatleads to an addition polymer is to add a source of a freeradical to the monomer. The term free radicalis used to describe a family of very reactive, short-livedcomponents of a reaction that contain one or more unpairedelectrons. In the presence of a free radical, addition polymersform by a chain-reaction mechanism that containschain-initiation, chain-propagation, and chain- terminationsteps.
At first glance we might expect the product of thefree-radical polymerization of ethylene to be a straight-chainpolymer. As the chain grows, however, it begins to fold back onitself. This allows an intramolecular reaction to occurin which the site at which polymerization occurs is transferredfrom the end of the chain to a carbon atom along the backbone.

Because the intermediates involved in ionic polymerizationreactions can't combine with one another, chain termination onlyoccurs when the growing chain reacts with impurities or reagentsthat can be specifically added to control the rate of chaingrowth. It is therefore easier to control the average molecularweight of the product of ionic polymerization reactions.
