This makes it a special case in the comparison between condensation and addition polymers.
Addition polymers are also formed from monomers having closed ring.
Through coordination polymerization, even saturated monomers can form addition polymers.
Addition polymers form high molecular weight chains rapidly, with much monomer remaining.
Most of the common addition polymers are formed from unsaturated monomers (usually having a double bond).
In general, condensation polymers form more slowly than addition polymers, often requiring heat.
An addition polymer is formed by the reaction termed as polyaddition or addition polymerization.
To alleviate inconsistencies in these naming methods, adjusted definitions for condensation and addition polymers have been developed.
With exception of combustion, the backbone of addition polymers are generally chemically inert.
This method, however, is expensive and inefficient, so the addition polymer of ethene (polyethylene) is generally used.
Condensation polymers, unlike addition polymers, may be biodegradable.
An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.
Consider the transition metal catalysts that catalyse the polymerization of alkene monomers (such at ethene and propene) to form addition polymers.
This is due to the very strong C-C and C-H bonds and lack of polarisation within many addition polymers.
The first useful addition polymer was made by accident in 1933 by Imperial Chemical Industries chemists Reginald Gibson and Eric Fawcett.
An 'addition polymer' is a polymer which is formed by an addition reaction, where many monomers bond together via rearrangement of bonds without the loss of any atom or molecule.
Most step-growth polymers are also classified as condensation polymers, but not all step-growth polymers (like polyurethanes formed from isocyanate and alcohol bifunctional monomers) release condensates; in this case, we talk about addition polymers.
Condensation polymers are any kind of polymers formed through a condensation reaction-where molecules join together--losing small molecules as by-products such as water or methanol, as opposed to addition polymers which involve the reaction of unsaturated monomers.
