Polymers: an overview. When many molecules of a simple compound join together, the product is termed a polymer and the process polymerization. The simple compounds whose molecules join together to form the polymers are called monomers. The polymer is a chain of atoms, providing a backbone, to which atoms or groups of atoms are joined.
The term polymer is derived from the Greek poly, meaning many, and mer, meaning parts  thus polymers are substances made of many parts. In most cases the parts are small molecules which react together hundreds, or thousands, or millions of times. molecule used in producing a polymer is a monomer  mono is Greek for single, thus a monomer is a single part. A polymer made entirely from molecules of one monomer is referred to as a homopolymer. Chains that contain two or more different repeating monomers are copolymers.
