Paper Abstract

Polymeric materials, specifically polyurethanes, have been investigated with the use of mid- infrared transmitting fibers. The fibers are used as internal reflection elements for attenuated total reflectance (ATR) spectrometry. Fourier transform infrared (FT-IR) spectrometers were used to collect the data. Spectra were collected at rates of three spectra per second to 5 seconds per spectrum. The spectral bandpass of the systems was from approximately 5500 cm-1 to 850 cm-1. Not only was the reaction chemistry monitored, but chemical morphological changes were recorded as well. Water slabstock polyurethane foams were studied as were reaction injection molded (RIM) polyurethanes.
