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 addition polymer give an example?
Examples- Polyethylene, Polyvinyl Chloride, Teflon, Rubbers (Buna-N, Buna-S), Polyacrylonitrile. In this reaction, n molecules of tetrafluoroethylene are polymerized to form Teflon.
What is addition polymerization give two example?
(a) An addition polymer is formed by chain growth polymerization. The addition polymer contains all atoms of monomers. The monomers are alkenes. Examples of addition polymers include Orlon, Teflon, PVC, Polythene etc. . Thus, polymerisation of vinyl cyanide gives Orlon.
How do you identify addition polymers?
The main difference between addition and condensation polymerization is that in addition polymerization the polymers are formed by the addition of monomers with no by-products whereas in condensation polymerization, the polymers are formed due to the condensation more than one different monomers resulting in the …
What are addition polymers give Example Class 12?
The addition polymers are formed by the repeated addition of monomer molecules possessing double or triple bonds, e.g., the formation of polythene from ethene and polypropene from propene.
What are addition polymerization steps?
Addition or chain polymerisation can be divided into 3 steps – initiation, propagation, and termination.
What are addition polymers give two examples Class 12?
Addition polymers The addition polymers are formed by the repeated addition of monomer molecules possessing double or triple bonds, e.g., the formation of polythene from ethene and polypropene from propene.
What is meant by addition polymerization?
In polymerization. In addition polymerization, monomers react to form a polymer without the formation of by-products. Addition polymerizations usually are carried out in the presence of catalysts, which in certain cases exert control over structural details that have important effects on the properties of the polymer.
How do you do addition polymers?
Addition polymers can be formed by chain polymerization, when the polymer is formed by the sequential addition of monomer units to an active site in a chain reaction, or by polyaddition, when the polymer is formed by addition reactions between species of all degrees of polymerization.
What are addition polymers used for?

Is Bakelite an addition polymer?
Addition polymer: the polymer which is a synthesis based on addition polymerization is known as addition polymers. Hence, Bakelite is a type of condensation polymer. The correct answer is option C. Note: Bakelite is the commercial name for the phenol-formaldehyde resin.
What is an example of an addition polymer?
Examples of such polyolefins are polyethenes, polypropylene , PVC, Teflon , Buna rubbers, polyacrylates , polystyrene , and PCTFE. When two or more types of monomers undergo addition polymerization, the resulting polymer is an addition copolymer.
How are addition polymers formed?
Addition polymers can be formed by chain polymerization, when the polymer is formed by the sequential addition of monomer units to an active site in a chain reaction, or by polyaddition, when the polymer is formed by addition reactions between species of all degrees of polymerization.
What are additional polymers?
The polymer is a long chain molecule which is formed by joining many small molecules called monomers. Addition polymers are a type of polymer in which all the monomers are unsaturated or to simply to say are alkenes.
What is addition polymerization?
Polymerization that occurs through the coupling of monomers using their multiple bonds is called addition polymerization. The simplest example involves the formation of polyethylene from ethylene molecules.
