Assessing Formulation in Polymeric Materials by ATR-FTIR
6 Feb 2012
In this study semi-rigid polyurethane samples were analyzed by ATR/FTIR. These samples contained varying ratios of isocyanate to alcohol monomers. The polyurethane sample was placed over the ZnSe crystal, and high pressure was applied. Spectral range covered 4000 to 520 cm-1. Spectra were collected at 4 cm-1 spectral resolution utilizing a 1 minute data collection time. No sample preparation was required and samples were run at room temperature.
