Monomer
Term: Monomer
Category: Chemistry
Definition: A monomer is a small molecule that acts as a building block for larger molecules called polymers. Monomers join together through a chemical process called polymerization to make long chains or networks. Each monomer usually has one or more reactive parts (functional groups) that let it connect to other monomers. The order and types of monomers in a chain decide the polymer’s shape, strength, and other properties.
How it Works: Monomers react through addition or condensation polymerization processes.
- Addition polymerization: Monomers with double bonds add to one another without forming by-products.
- Condensation polymerization: Monomers with two reactive ends combine while releasing small molecules such as water or methanol.
This repeated bonding produces polymers with specific chain lengths and properties tailored for desired applications.
Common Uses:
- Production of biocompatible polymers for medical implants and devices
- Synthesis of hydrogels and drug delivery systems
- Manufacturing of biodegradable plastics and coating materials
- Formation of adhesives, elastomers, and nanocomposites in biomedical and industrial applications
