A monomer is the molecular unit from which polymers are prepared. A polymer is a molecular chain formed by combining many smaller molecules. Polymers are the product of a reaction called polymerization, the process of connecting many (poly) single units (mers or mono-mers) to form long chain molecules of higher molecular weight.
