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) chain Polyethylene Varieties Milk bottles, detergent bottles, oil bottles, toys, & plastic grocery bags Shrink-wrap films, sandwich bags, garment bags, grocery bags Bottle caps Polyethylene Varieties Milk bottles, detergent bottles, oil bottles, toys, & plastic grocery bags Shrink-wrap films, sandwich bags, garment bags, grocery bags Bottle 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 H 2 O. +  +

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
