Infrared Spectroscopy of Polymers XIII: Polyurethanes

Abstract

We continue our survey of the spectra of nitrogen containing polymers with a look at polyurethanes. Polyurethanes are widely made into foam rubber, elastic, and wood coatings, amongst other things. The spectra of polyurethanes are similar to polyamides since both polymer types contain C=O and N-H bonds. Therefore, we will begin with a review of the spectra of polyamides.
