polycondensation

In chemistry, polycondensation refers to a type of reaction where two molecules react with each other to form a larger molecule, releasing a smaller molecule such as water, ammonia, or some other simple compound. Polycondensation reactions can occur in organic and inorganic chemistry and are used to produce polymers, resins, ceramics, metals, and other materials.

A well-known example of a polycondensation reaction is the production of polyester. Here, a reaction between a dicarboxylic acid ester and a diol is carried out, with water being released as a by-product. The reaction results in the formation of a polyester polymer with a linear or branched structure that can be used in the manufacture of textiles, films, coatings, and other products.

Polycondensation reactions are often of great importance in materials science and can be used to produce polymers.
