POLYMERS

POLYMERS

1. Plastics

   • Polyester
   • Nylon
   • PVC
     • PolyVinylChloride
       • -CH2-CHCl-
   • Polysterine
   • Bakelle
   • TEFLON
     • Which is PTFE: polytetrafluoroethene
       • Fluorine extreme electronegativity makes it frictionless

2. Hydrogen conection

3. Natural

   • Polysaccharides
   • Monomers
     • Amino-Acids

4. Celluloid

   • Invented to replace ivory of the elephant's horns, which was used to make billiard balls
     • Nowadays use varies from
       • Piano keys
       • Artificial tooth
       • Others
   • Invented by
     • John Wesley Hyatt
       • By mixing
         • Cotton
         • Nitric Acid

5. Chains or 3D networks of repeated oganic units

   • Monomers
   • The amount of chains determines it's strength
   • Examples
     • Ethene
       • Polymerization
     • Polyethene
