Polymär

Polymér is a chemical compound or substance that has a molecular structure built by repeating smaller units. These smaller units are called monomers. The process of forming these larger molecules from monomers is known as polymerization. Polymers can be natural, such as cellulose and proteins, or synthetic, like polyethylene and nylon. The properties of a polymer depend on the type of monomer used, the length of the polymer chain, and how the chains are arranged. This variability allows for a wide range of applications, from plastics and fabrics to adhesives and coatings.

The discovery and development of synthetic polymers revolutionized many industries in the 20th century. Early examples include bakelite and celluloid, which paved the way for modern plastics. The chemical structure of polymers can be linear, branched, or cross-linked, influencing their physical characteristics such as strength, flexibility, and melting point. Understanding polymer chemistry is crucial for designing materials with specific performance requirements. Researchers continue to explore new polymer structures and polymerization techniques to create advanced materials for emerging technologies.
