Product Details

We use polymers every day! In fact, it is difficult to identify items that do not contain polymers. Despite their tremendous variety, all polymers are basically made by either addition or condensation reactions. Three independent “mini-lab” activities are included in this lab kit. Each activity takes about 10–15 minutes to complete, and students may rotate through the activity stations in any order. Students will synthesize three common polymers—nylon, polyurethane and polyester—and compare and contrast the methods of preparing them and their properties. All procedures have been microscaled and simplified to make them suitable for the high school laboratory. The activity-stations format is perfect for this introduction to polymers lab, allowing you to do more labs in less time.

Complete for 27 students working in groups of three. Perform this experiment in a fume hood or well-ventilated lab.
