What are natural and synthetic polymers? Give two examples of each type

Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.

Synthetic polymers are derived from petroleum oil, and made by scientists and engineers. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy.

A polymers which occurs in nature are called natural polymers which includes silk, wool, DNA, cellulose and proteins. While synthetic polymers are those polymers which are derived from petroleum oil which includes nylon, polyethylene, polyester, Teflon and epoxy.
