How to Create a Stretchy Polymer: A Guide

Option 2: Create a polymer with the longest stretchTo test the “stretchiness” of your polymer, we will use a meter stick as well. For the test, hold one end of the putty and allow gravity to stretch the material. Measure the length of the putty before it breaks.Complete three separate stretch testsand find the average length.ObservationsIn this section, you need to includetwo things:1.Aqualitative description of your final polymer2.A graph that shows the stretch/test results throughout your design process. (I would recommend using Microsoft Excel for this graph). This can be any type of graph you think would represent this data the best. Discussion Questions1.How does the addition of sodium borate change the physical properties of thepoly(vinyl alcohol) solution?Explain using what you know aboutchemical bonding.2.Below you can see the reaction mechanism for the cross-linking reaction. What type of organic reaction is present in step 5?3.In your own words, explain what a polymer is. 4.Give an example of a commercial product that is made from a polymer.Explain how the underlying intermolecular and intramolecular structure of the selected polymer meet the needs of the purpose of the product. 5.What measures could you have taken to improve your design further? Explain how these changes would have helped make the putty more stretchy/bouncy.
