Question

What are polymers?

Answer 1

1. Polymers are high molecular mass macromolecules, which consist of repeating structural units derived from monomers.
2. Polymers have a high molecular mass (10³-10⁷ u). In a polymer, various monomer units are joined by strong covalent bonds.
3. These polymers can be natural as well as synthetic.
4. Polythene, rubber, and nylon 6, 6 are examples of polymers.

Answer 2

1. Polymers are large molecules made by the repeated combination of small units called monomers.
2. This process of joining monomers is called polymerisation.
3. Polymers can be natural (like proteins, starch) or synthetic (like polythene, nylon).
4. They have high molecular mass and are used in making plastics, fibres, and rubbers.
