What are possible polymer chemistry experiments?

[Sam Donovan]

I was wondering if there were any possible experiments that I can conduct in a high school lab setting.

To demonstrate cross-linking reactions, you can use Durham's Wood Putty. Once you add the water, you can feel the heat od the exothermic reaction. Shape into any shape, and let harden.

Another example is auto body filler and hardener. You mix the two, and they watch it set up

Both are easy access and inexpensive.
