Polymer
Polymers are compound of extremely high molecular masses made by the combination of a large number of simple molecules.
The simple molecules that combine to offer polymers are termed as monomers. The method through which the simple molecule (i.e. monomers) is transformed into polymers is known polymerisation.
For instance: Polyethylene
1. All polymers are macromolecule although all macromolecules are not polymers as polymer consist repeating unit of monomer for example chlorophyll is a macro atom although not a polymer.
