Polymers

Polymers (/pɒlɪmərz/; from Greek poly-, "many" + -mer, "part") are substances or material consisting of very large molecules, or macromolecules, composed of many repeating subunits. Due to their broad range of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.

Etymology

The term "polymer" derives from the ancient Greek word πολύς (polus, meaning "many, much") and μέρος (meros, meaning "parts"), and refers to a molecule whose structure is composed of multiple repeating units, from which originates a characteristic of high relative molecular mass and attendant properties.

Types of Polymers

Polymers are of two types: Natural Polymers and Synthetic Polymers. Natural polymers include proteins, starch, and cellulose. Synthetic polymers include plastics, synthetic fibers, and synthetic rubber.

Natural Polymers

Natural Polymers are those which are found in nature. They are formed by nature in different ways. Examples include proteins, starch, and cellulose.

Synthetic Polymers

Synthetic Polymers are those which are man-made. They are derived from petroleum oil and made by scientists and engineers. Examples of synthetic polymers include plastic, synthetic fibers, and synthetic rubber.

Properties of Polymers

Polymers have unique properties depending on the types and arrangement of monomer units along the polymer chain. These properties can include strength, flexibility, and resistance to chemicals and heat.

Applications of Polymers

Polymers have a wide range of applications that include but are not limited to: packaging materials, textiles, non-stick pans, and medical devices.
