Important terms and points of Class 12 Chemistry chapter 15 Polymers-

1. Polymers-  They are very high molecular mass macromolecules, which composed of repeating structural units derived from the monomers. Polymers have a high molecular mass (10^3-10^7U). Rubber, polythene, and nylon 6, 6 are examples of polymers.

2. Monomers- Monomers are the simple and reactive molecules that combine in large numbers through covalent bonds to give rise to the repeating structural units or polymers. For example propene, vinyl chloride, styrene, etc.
