Write two differences between natural and synthetic polymers.

Explanation

Natural polymers. Polymers which are found in natural living organisms, i.e., animals and plants are called natural polymers. They are biodegradable. For example, proteins, starch, cellulose, nucleic acids, resins and rubber.
Synthetic polymers. Man-made polymers are called synthetic polymers. They are generally non biodegradable. For example, plastics (Polythene, PVC), synthetic fibres (Polyester, Nylon 6,6), synthetic rubber (Neoprene, Buna-s), etc.
