WebPolymer is a peer-reviewed scientific journal covering all aspects of polymer science.It is published by Elsevier and the editor-in-chief is Benny Freeman (University of Texas at … WebPolymers are long chains of atoms bonded to each other. In most plastics, the long chain is a chain of carbon atoms with other atoms attached to them. The different atoms and the shape and length of the chains change how the plastic looks and works. People experimented with plastics based on natural polymers for a very long time.
