WebFor example, divide students into 5 groups. Have one group add 2 ml of borax to 100 ml of PVOH solution. The others groups should add 4, 8, 12, and 20 ml of borax to the 100 ml of polymer solution, respectively. This should more easily demonstrate the effects of crosslinking on the properties of the polymer.
