👉 Polycondensation is a chemical process in which two or more organic compounds react with one another to form a single compound, typically a polymer. This reaction involves the addition of a monomer (a type of organic molecule) to another monomer, resulting in the formation of a new compound that has a different molecular structure from both its starting components. Polycondensation is commonly used in various industries such as rubber, plastics, and fibers for their versatility and properties.
