Polymer

A polymer is a large molecule composed of repeating structural units called monomers. These monomers are covalently bonded to form long chains, and the process by which they are linked together is known as polymerization. Polymers can be natural or synthetic and are essential in our daily lives, as they are used in a wide range of materials and products.

Natural Polymers

Natural polymers are found in living organisms and include substances such as proteins, cellulose, and DNA. These polymers play crucial roles in biological processes and are biodegradable, making them environmentally friendly.

Synthetic Polymers

Synthetic polymers are human-made and are widely used in various industries. Examples of synthetic polymers include plastics, synthetic fibers, and rubber. These polymers are often designed to have specific properties such as strength, flexibility, and durability.
