1. Organic Chemistry
POLYMERS

2. A- Polymer A1. Poly = many A2. Mer = units
A3. Polymers are large molecules that has many units bonded together
A4. The individual units made up the polymer are called monomers

3. B- Natural Polymers
Amylose (in starch)
DNA

4. B- Natural Polymers (Cont’d)
Protein

5. C-Man-made or Synthetic Polymers
C1. Type 1: Addition polymers
C2. Made by addition reaction of monomers that have double bonds or triple bonds

6. D-Properties of Addition Polymers
D1. Stable as the double bond converted to single bond
D2. Flexible, stretchable and mouldable thanks to lots of weak, intermolecular forces that hold the long polymer chain together

7. D- Properties of Addition Polymers (Cont’d)
D3. Addition polymers can also cross-link with one another if extra double bonds are present
D4. The more crosslinks occur, the more rigid the polymers

8. E- Plastic bag- How it’s made???
E1. Made from a polymer
called polyethylene
E2. Take 1 million year to break down/ degrade a plastic bag
E3. What do you think of our Toronto’s recent 5cent/plastic bag policy?

10. F- Common Addition Polymers

11. G- Another Man-made Addition Polymer
G1- The super absorbent polymer is Polyacrylic acid
Video

12. H- Super absorbent Polymer (Cont)
H1. absorb up to 1,000 g of water per gram of polymer

13. I- Man-made or Synthetic Polymers (cont’d)
I1. Type 2: Condensation polymers
I2. Made by condensation reaction in which monomers are joined and water is produced

14. J- Natural condensation polymers

15. K- Properties of Condensation Polymers
K1. Has the ability to hydrogen bonds thanks to the C=O groups
K2. Thus making condensation polymer very strong
K3. Kevlar: a polyamide, condensation polymer that is stronger than steel
K4. Kelvar is used to make aircraft parts, sport equipment, protective clothing, bullet proof vests for policemen

16. L- Hydrogen bonding in Condensation Polymers
L1. HYDROGEN BONDING IN PROTEINS
L2. HYDROGEN BONDING IN Kevlar

17. M- Some common
condensation polymers

18. N- Applications of Nylon
N1. Invented by Dupont
N2. Nylon stands for New York
& London
N3. Tear resistant
N4. Water-proof
Used in making
parachutes
stocking
sleeping bags
tent, sail
cooking utensils
Nylon = New York and London where the research on Nylon was being done. Interesting.

19. N- Nylon
N5. Watch synthesis movie

20. O- Silicone as polymer Silicone based baking pan
Traditional metal baking pan
Silicone breast implant
Silicone structure

22. Q- POLYMER TIME! Making slime
Pour Elmer Glue to the mark in a plastic cup
Add equal volume of water to dissolve the glue
Add desire food colorant
Stir
Add prepared Borax solution DROPWISE until the slime is somewhat thicken
Don’t add too much Borax
