What is exactly a polymer?

I'm a college freshman, so my knowing about chemistry is not much. I want to know exactly what a polymer is, how does it work, and how is it formed. Thanks!

Re: What is exactly a polymer?

Polymer is a large molecule made of repeating units that are called monomers; The process of joining together of repeat unit monomers is called polymerization.  The word polymer is derived from Greek word Poly-  which means many.

Polymers can be made by  various methods such as condensation polymerization, free radical polymerization, addition polymerization, copolymerization etc. 

What makes polymers fascinating is  that various monomers can be used to engineer desired  and unique properties in polymers such as heat resistance, tensile strength, high impact resistance, toughness , low surface tension etc.  Most modern engineered materials utilize innovative polymers in vast areas of applications,  and are developed by polymer chemists and polymer and material scientists. 

Polymer Chemistry is a fascinating field.
