Pre Lab #15 Polymer synthesis Addition polymer—Polystyrene 1. Place 20 drops of styrene into a disposable 13 x 100 mm test tube 2. Wear gloves! 3. Use a wooden or plastic utensil tad to add a few grains of dibenzoyl peroxide and shake the tube to the mix. 4.

When the material in the test tube has turned slightly yellow, remove the test tube from the sand bath and cool it on ice. 7. Try to shake the polymer out of the test tube. 8. Wear gloves when doing this! 9. Describe the appearance and properties of your polymer. 10. Test the solubility of the polymer by grinding a few chunks in a mortar and pestle and placing the powder in two test tubes. 11. Add water to one of the test tubes and acetone to the other test tube. 12. Record your observations. 13. Dispose of the acetone mixture in the appropriate Laboratory Byproducts Jar.
