Polymers are large molecules, or macromolecules, composed of many repeating subunits called monomers. These monomers are linked together through covalent bonds, creating long chains or networks with diverse properties. The specific arrangement and type of monomers determine the polymer's characteristics, including its flexibility, strength, melting point, and solubility. polymers are ubiquitous in nature, found in substances like cellulose (in plants), proteins (in animals), and DNA (the genetic material). They are also extensively synthesized by humans for a wide range of applications, from plastics and rubber to adhesives and textiles, making them crucial materials in modern technology and everyday life.
Polymers meaning with examples
