Explainer: What are polymers? | Science News for Students

Polymer chains can include hundreds of thousands of atoms — even millions. The longer a polymer chain, the heavier it will be. And, in general, longer polymers will give the materials made from them a higher melting and boiling temperature. Also, the longer a polymer chain, the higher its viscosity (or resistance to flow as a liquid). The ...
