Topic: Polymerization
Polymerization
• Reaction that produces very large molecules (poly = many) consisting of many small, repeating structural (monomers)
Addition Polymerization• Start with one unsaturated monomer, and
keep adding until you have a long (poly) chainPolyethylene Varieties
Milk bottles, detergent bottles, oil bottles, toys, & plastic grocery bagsShrink-wrap films, sandwich bags, garment bags, grocery bagsBottle caps
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.

SLIME (Glue + Borax)
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)!!!!!
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
