Infrared Spectroscopy of Polymers, VIII: Polyesters and the Rule of Three
Brian C. Smith
Abstract
In the last column, we reviewed the spectroscopy of the carbonyl group and that of ketones. We then analyzed our first C=O containing polymer. In this column, we continue to study C=O containing polymers by first reviewing the spectroscopy of the ester functional group and then analyzing the spectra of several important polyesters. Among the spectra we study is that of polyethylene terephthalate (PET), one of the most economically important polymers in the world.
