Frequently Asked Questions | FAQs

What is an example of condensation polymerization?

An example of condensation polymerization in textile manufacturing is the production of polyester fibers. Polyester is a popular synthetic fiber used in textiles due to its durability, wrinkle resistance, and moisture-wicking properties. It is commonly used in clothing, upholstery, and other textile applications.

The condensation polymerization process for producing polyester fibers typically involves two monomers, a dicarboxylic acid and a diol. Examples of dicarboxylic acids used in polyester production include terephthalic acid and adipic acid, and examples of diols include ethylene glycol and propylene glycol.

During the condensation polymerization process, the dicarboxylic acid and diol react with the elimination of a small molecule, such as water or methanol, as a byproduct. This reaction forms ester bonds between the monomers, resulting in the formation of a long-chain polymer.

The polymerization reaction is typically carried out under controlled conditions, such as high temperature and low pressure, with the addition of a catalyst to facilitate the reaction. Once the polymerization is complete, the resulting polyester polymer can be spun into fibers, which are then used in various textile applications.
