उत्तर
- A large molecule (macromolecule) formed by linking many repeating smaller chemical units called monomers.
- The chemical reaction that binds these monomer chains together is called polymerisation.
- Found in nature, essential for life (e.g., cellulose, proteins, DNA, and natural rubber).
- Man-made materials, usually derived from petroleum (e.g., plastics like polythene, PVC, nylon, and Teflon).
- Their unique, long-chain structures make them highly versatile. Depending on their makeup, they can be anything from stretchable and flexible to incredibly tough and heat-resistant.
