1. Organic Chemistry POLYMERS

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

3. Natural Polymers Amylose (in starch) DNA

4. Natural Polymers (Cont’d) Protein

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

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

7. Plastic bag- How it’s made??? Made from a polymer called polyethylene Take 1 million years to break down/ degrade a plastic bag

8. Another Man-made Addition Polymer The super absorbent polymer is Polyacrylic acid

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

10. Applications of Nylon Invented by Dupont Nylon stands for New York & London Tear resistant Water-proof Used in making: parachutes stocking sleeping bags tent, sail cooking utensils

11. Silicone as polymer Silicone based baking pan Silicone breast implant Traditional metal baking pan Silicone structure

12. 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
