The Infrared Spectra of Polymers III: Hydrocarbon Polymers

We continue to examine the spectra of polymers because they are important materials, and this exercise makes for an excellent infrared (IR) spectral interpretation review. In this installment, we look at the spectra of more hydrocarbon polymers, including polypropylene and polystyrene. We look at the IR spectra of these materials in detail, and see how IR spectroscopy can be used to distinguish them from each other.
