Difference Between Prepolymer and Oligomer

The key difference between prepolymer and oligomer is that a prepolymer is an intermediate of a polymerization reaction, whereas an oligomer is a polymer material composed of comparatively a few monomer units. Therefore, a prepolymer is an intermediate compound, while an oligomer is a final product.

What is the difference between monomer and oligomer?

A monomer can be defined as a molecule that can combine with other molecules to form an oligomer or polymer. An oligomer can be described as a molecular complex comprised of a few monomer units.

What is meant by oligomer?

In chemistry and biochemistry, an oligomer (/əˈlɪɡəmər/ ( listen)) is a molecule that consists of a few similar or identical repeating units which could be derived, actually or conceptually, from copies of a smaller molecule, its monomer.

Is a dimer and oligomer?

A dimer (/ˈdaɪmər/) (di-, "two" + -mer, "parts") is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular. ... The reverse of dimerisation is often called dissociation.

What do oligomers do?

Oligomers are essentially intermediates of the polymerization reaction that find wide, direct applications in material science. Oligomers can be grouped into addition oligomers and condensation oligomers, based on the structure of the repeating unit.

What are oligomers called?

Dimers, trimers, and tetramers are, for example, oligomers respectively composed of two, three, and four monomers. The oligomer is regarded as having an intermediate molecular weight if it has properties which do vary significantly with the removal of one or a few of the units.

What is the meaning of trimer?

trimer in American English

(ˈtraɪmər ) noun Chemistry. 1. a molecule composed of three identical, simpler molecules. 2.

What are polymerization reaction?

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.

Is glucose a dimer?

One of the most common disaccharides is sucrose, which is common table sugar and is shown in Figure 5.10a. It is a dimer of glucose and fructose. ... Maltose (5.10c) is also a sugar dimer but is a product of starch digestion. It is a dimer made up of glucose and glucose.

Why does AlCl3 exist as dimer?

AlCl3 exists as a dimer as the Al atom in the molecule is electron deficient due to presence of only 6 electrons in its' valence shell ie it has an incomplete octet due to which it is quite unstable. ... The dimer so formed (Al2Cl6) is more stable and undergoes milder reactions than the monomer AlCl3.

What is the process of dimerization?

What is dimerization? It is a process where two molecules of similar chemical composition come together to form a single polymer known as a dimer. Where does dimerization occur? ... In the nucleus, hormone receptors, acting as transcription factors, form dimers to increase stability and improve binding to DNA.
