What is called a natural polymer and why?

Dear student,

Natural polymers are polymers that are found in nature. They are formed by plants and animals. Examples include protein, cellulose, starch, etc.

Synthetic polymers are polymers made by human beings. Examples include plastic (polythene), synthetic fibers (nylon 6, 6), synthetic rubbers (Buna − S).

Natural polymers are called as natural polymers because they are obtained from the nature.
