define polymers in detail??
Answers
Explanation:
A polymer is a large molecule made up of chains or rings of linked repeating subunits, which are called monomers. Polymers usually have high melting and boiling points. Because the molecules consist of many monomers, polymers tend to have high molecular masses.
The word polymer comes from the Greek prefix poly-, which means "many," and the suffix -mer, which means "parts." The word was coined by Swedish chemist Jons Jacob Berzelius (1779–1848) in 1833, although with a slightly different meaning from the modern definition. The modern understanding of polymers as macromolecules was proposed by German organic chemist Hermann Staudinger (1881–1965) in 1920.
Examples of Polymers
Polymers may be divided into two categories. Natural polymers (also called biopolymers) include silk, rubber, cellulose, wool, amber, keratin, collagen, starch, DNA, and shellac. Biopolymers serve key functions in organisms, acting as structural proteins, functional proteins, nucleic acids, structural polysaccharides, and energy storage molecules.

Answer:
Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded .
Some polymers bend and stretch, like rubber and polyester. Other are hard and tough, like epoxies and glass.
