The Polymer Explosion: Crash Course Engineering #20
We’re continuing our look at engineering materials with third main type of material that you’ll encounter as an engineer: polymers. They’re made of long, repeating chains of smaller molecules known as monomers and today we’ll explore their strange history of polymers and the things that contributed to how we use them today.
