|---|---|---|---|---|---|
| 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 thermoplastic polymer? | A kind of polymer that can be heated and reshaped. Not all polymers can be thermoplastic ones.
🗑
|
||||
| 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.
🗑
