FIGURE 1. Fourier-Transform Infrared spectrograph of the three existing polymers. Wavenumber refers to the wavelength of light and % Transmission refers to the amount of each wavelength that is transmitted through the sample. These are the parameters measured by the spectrometer to achieve an infra-red spectrum. Each peak is indicative of a different chemical bond and different substances will produce distinct patterns.
