What is a polymer? Is made out of smaller molecules called monomers.
What is a monomer? A small molecule building block from which polymers are made.
Give examples of polymers. Starches and proteins in food, Wood for shelter, and Silk in clothes.
What is a celluloid? Cellulose nitrate, a synthetic material drived from natural cellulose by treating with nitric acid. Very Flammable.
What are uses for celluloid? Billard balls, movie film. Replaced ivory.
What is polyethylene? The simplest and least expensive synthetic polymer.
What are uses for polyethylene? Plastic bags for fruit, garment bags for dry-cleaned clothes.

What is a thermosetting polymer? A kind of polymer that hardens permanently when formed and cannot be softened by head and remolded.
What is vulcanization? The process of making naturally soft rubber harder by reacting it with sulfur.
How does vulcanization work? Long-chained molecules are coiled and twisted and intertwined with one another. This is how you could stretch rubber but it'll snap back to normal.
What is polyester? A condensation polymer made from molecules with alcohol and carboxylic acid functional groups.
What are polyester fibers? They are strong quick-drying and resistant to mildew, wrinkling, stretching, and shrinking. (NOT TOO IMPORTANT)
What can silicons be? Silicons can be linear, cyclic, or cross-linked networks. They are heat-stable and resistant to most chemicals and are excellent waterproofing materials.
Are silicons oils, rubbery, or solid? They are all of them, depending on the chain length and amount of cross-linking.
