Presentation Transcript

  1. Topic: Polymerization

  2. Polymerization • Reaction that produces very large molecules (poly = many) consisting of many small, repeating structural (monomers)

  3. Addition Polymerization Polyethylene Varieties Milk bottles, detergent bottles, oil bottles, toys, & plastic grocery bags Shrink-wrap films, sandwich bags, garment bags, grocery bags Bottle caps • Start with one unsaturated monomer, and keep adding until you have a long (poly) chain

  4. Condensation Polymerization (aka – dehydration) • Condensation = water • Water is a product • monomers containing 2 functional groups combine with the loss of a small by-product, usually H2O. +  +

  5. Nylon

  6. SLIME (Glue + Borax)

  7. Slime • ½ bottle of glue – add 5 drops of food coloring– fill the other half of bottle with warm water • In the small beaker add 120 ml warm water and ½ teaspoon of borax • Pour glue/water mixture into mixing bowl and slowly add borax(aq) – use your hands to mix – add borax(aq) until desired slimeyness – DON’T ADD ALL BORAX(aq)!!!!!

  8. Conclusion Paragraph : Lab 27 • Explain how an polymerization reaction works • Give 4 polymers you have used • What is the difference between an addition and condensation polymerization • In terms of size, compare polymers to other organic molecules. • In order to get glue to form into a polymer, Borax was need. What role did Borax play in helping create the slime polymer
