POLYESTERIFICATION Meaning and
Definition
-
Polyesterification refers to a chemical process in which individual monomer units, usually containing ester groups, combine to form a polymer known as a polyester. This reaction occurs through a condensation reaction between the hydroxyl group (–OH) of one monomer and the carboxylic acid group (–COOH) of another monomer, resulting in the formation of an ester linkage (–COO–) and the release of a water molecule.
Polyesterification is typically achieved by heating a mixture of monomers, known as a polycondensation reaction, in the presence of a catalyst or by employing high pressure. The reaction proceeds until the desired degree of polymerization is reached, leading to the formation of long chains of repeating ester units.
Polyesterification has found extensive applications in the production of various types of synthetic fibers, fabrics, films, and resins. Polyester fibers, such as PET (polyethylene terephthalate), are widely used in the textile industry due to their excellent strength, durability, and resistance to wrinkles, shrinking, and fading. Polyester resins are commonly employed in the manufacturing of plastic bottles, packaging materials, and coatings due to their chemical and mechanical properties.
The polyesterification process is crucial in the creation of these materials as it allows for the control of polymer chain length, which dictates the final properties of the resulting polyester.

Etymology of POLYESTERIFICATION
The word "polyesterification" is a combination of two separate terms: "polyester" and "esterification".
The term "polyester" is derived from the combination of "poly-" (meaning "many" or "multiple") and "ester". "Ester" refers to a chemical compound created through the reaction between an alcohol and an organic acid, resulting in the formation of an ester bond. Polyesters are a category of polymers formed by multiple ester groups linked together.
On the other hand, "esterification" comes from the word "ester", with the suffix "-ification" added. Esterification is a chemical reaction that involves the formation of an ester by combining an alcohol and an organic acid in the presence of a catalyst.
Therefore, "polyesterification" combines these two terms to refer to the process of forming or synthesizing polyesters through the esterification reaction.
