condensation polymerization

chemistry

Quick Summary

Condensation polymerization is a chemical process where monomers, or small molecules, link together to form a large polymer chain. Unlike addition polymerization, condensation polymerization involves the elimination of a small molecule, often water, with each step of the process.12

This type of polymerization is used to create various synthetic resins, such as phenol-formaldehyde, urea-formaldehyde, and melamine-formaldehyde. These resins are formed using formaldehyde and other monomers like phenol, urea, or melamine. The resulting polymers are thermosetting, meaning they form permanent three-dimensional networks that do not melt upon reheating and are widely used as adhesives in wood products and as plastics.3
