Which process is being describes condensation polymerization?

3 Condensation polymerization. Polycondensation is the term used to describe polymers formed as a result of reactions involving the condensation of organic materials in which small molecules are split out.

What is polymerization describe addition polymerization and condensation polymerization?

Addition polymerization is the process of repeated addition of monomers that possess double or triple bonds to form polymers. Condensation polymerization is a process that involves repeated condensation reactions between two different bi-functional or tri-functional monomers.

What is a condensation polymerization reaction?

When we talk about condensation polymerization, it is a form of a step-growth polymerization where smaller molecules or monomers react with each other to form larger structural units (usually polymers) while releasing by products such as water or methanol molecule.

How is addition polymerization different from condensation polymerization?

Difference Between Addition Polymerization and Condensation Polymerization. The key difference between addition polymerization and condensation polymerization is that for addition polymerization, monomer should be an unsaturated molecule whereas for condensation polymerization, monomers are saturated molecules.

Is condensation and addition reaction?

The addition of the two molecules typically proceeds in a step-wise fashion to the addition product, usually in equilibrium, and with loss of a water molecule (hence the name condensation).

What is polymerization explain condensation polymerization with the help of an example?

Condensation polymerizations are typical of monomers containing two or more reactive atomic groupings; for example, a compound that is both an alcohol and an acid can undergo repetitive ester formation involving the alcohol group of each molecule with the acid group of the next, to…

What are condensation and addition polymers?

A condensation polymer consists of two different kinds of monomers. An addition polymer is made when monomers bond to each other without the loss of atoms. A condensation polymer is formed when the monomers lose an atom or group of atoms while forming the polymer.

What are addition and condensation polymers explain with examples?

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 polymerization explain with example?

The chain grows by adding the reactive end of growing chain to double bond of monomer. Reactive intermediates such as free radicals, carbocations or carbanions are formed. An example of addition polymerisation is the polymerisation of tetrafluoroethylene (monomer) to form teflon (polymer).

How do condensation polymers form?

Which of the following is a condensation polymer?

Dacron, Nylon 6,6, and Nylon 6 are condensation polymers.

What is an addition reaction for polymers?

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.

Why is it called a condensation polymer?

Condensation polymers are those polymers that are formed from polyfunctional monomers, which are typically prepared by the reaction between two kinds of bifunctional symmetric monomers.

What is meant by the term condensation polymer?

Condensation polymer. (Science: chemistry) The kind of polymer that is formed by the combination of monomers and the release of a small molecules at the point where monomers are joined.

What is needed for condensation polymerization?

In addition polymerisation , the monomers must have a C=C double bond . However, in condensation polymerisation , the monomers do not need a C=C double bond but they do need two functional groups.

What is condensation polymerization Igcse?

Some polymers are made via condensation polymerisation . In condensation polymerisation, a small molecule is formed as a by-product each time a bond is formed between two monomers . This small molecule is often water. An example of a condensation polymer is nylon.
