The repeating structural unit of most simple polymers not only reflects the monomer(s) from which the polymers are constructed, but also provides a concise means for drawing structures to represent these macromolecules. For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation.
A macromolecule is a very large molecule commonly created by polymerization of smaller subunits (monomers).They are typically composed of thousands or more atoms.ccording to the standard IUPAC definition, the term macromolecule as used in polymer science refers only to a single molecule. For example,a single polymeric molecule is appropriately described as a macromolecule or polymer molecule rather than a polymer, which suggests a substance composed of macromolecules.
