This application note is the third of four parts summarizing the analysis of raw materials used in polyurethane production. This part focused on diisocyanates, as well as extenders and crosslinkers, which are two major components used to create polyurethanes. In this work, the identities and purities of various products were confirmed via
1H NMR spectroscopy.
