The Periodic Table of the elements by Mendeleev was a historic achievement in chemistry and enabled chemists to see the relationship between structure and properties of the basic elements. Polymers also have a strong relationship between structure and properties and this ‘Periodic Table of Polymers’ is a first attempt to provide a simple codification of the basic polymer types and structures. Thediversity of polymer types makes it impossible to include all of the variations in one simple table and this table only includes the most common polymers.
