POLYMER SYNTHESIS (POLYMERIZATION)
A chemical reaction which make polymers is called a polymerization.
Start with small molecules(monomer), and join them into big giant

Pliable/flexible, can be shaped and molded easily.
Easier to mold and shape when they're hot, and melt when they get hot enough.
Plastics tend to either deform permanently, or just plain break, when you stretch
them too hard

Introduction and History
Electron Microscopes are scientific instruments that use a
beam of highly energetic electrons to examine objects on a
very fine scale.
Electron Microscopes were developed due to the limitations
