Differbetween
The key difference between addition and radical polymerization is that the addition polymerization occurs via the addition of unsaturated monomers whereas the radical polymerization occurs via the addition of free radicals. Polymerization is the process of producing a polymer using a large number of monomers.

Difference Between Addition And Condensation Polymerization
| Addition Polymerization | Condensation Polymerization |
|---|---|
| Monomers must have either a double bond or triple bond | Monomers must have two similar or different functional groups |
| Produces no by-products | By-products such as ammonia, water and HCl are produced |
What is addition polymerization with example?
Addition polymers include polystyrene, polyethylene, polyacrylates, and methacrylates. Condensation polymers are formed by the reaction of bi- or polyfunctional molecules, with the elimination of some small molecule (such as water) as a by-product. Examples include polyester, polyamide, polyurethane, and polysiloxane.
What is meant by addition polymerization?
An addition polymer is a polymer that forms by simple linking of monomers without the co-generation of other products. Addition polymerization differs from condensation polymerization, which does co-generate a product, usually water. ... Addition polymers are formed by the addition of some simple monomer units repeatedly.
What are 2 types of polymerization?
There are two general types of polymerization reactions: addition polymerization and condensation polymerization. In addition polymerization, the monomers add to one another in such a way that the polymer contains all the atoms of the starting monomers. Ethylene molecules are joined together in long chains.
What are the 3 main types of polymers?
From the utility point of view they can be classified into three main categories: thermoplastics, elastomers and synthetic fibers. They are commonly found in a variety of products worldwide. A wide variety of synthetic polymers are available with variations in main chain as well as side chains.
What is polymerization process?
Polymerization, in polymer chemistry, is the process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains. There are many forms of polymerization and different systems exist to categorize them.
What is the first step in addition polymerization?
This process has three stages: initiation, propagation, and termination. In the first stage, a substance is split into two identical parts, each with an unpaired electron. (Peroxides, which contain an O-O bond, are often used in this role.) A molecule with an unpaired electron is called a free radical.
What happens in addition polymerisation?
Addition polymerisation is the type of polymerisation reaction that occurs when you take the monomers and simply add them together. That is the case with polymers such as poly(ethene) and poly(propene). The monomers join via a carbon-carbon double bond. No other chemicals are used up or made.
Why is PVC an addition polymer?
(c) Polymerization of chloroethene (vinyl chloride)
This is an example of addition polymerization. PVC is made by free-radical polymerization in suspension. ... During polymerization, the polymer precipitates out as it is formed, since it is insoluble in the monomer.
What are the three stages of addition polymerization?
Addition or chain polymerisation can be divided into 3 steps – initiation, propagation, and termination.
Is PVC an addition polymer?
Polyvinyl choride is abbreviated to PVC. ... Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene (vinyl chloride) monomer. This polymerisation reaction proceeds by a free-radical mechanism.
Is Terylene an addition polymer?
polymers : Terylene, Bakelite, polyvinyl chloride, polythene. Answer : Addition polymer : polyvinyl chloride, polythene condensation polymer : Bakelite, teryline.
