Diffuse reflectance ultraviolet spectra

Since the insolubility of the solid polymer precluded any ultraviolet studies in solution, attempts were made to obtain a diffuse reflectance spectrum of the solid. Meaningful data could not be obtained. Again, however, the liquid polymer could be compared with authentic polystyrene. Figure 4 shows the ultraviolet spectra of the two materials. Although the resolution is poor for the liquid polymer, its spectrum generally agrees with that of polystyrene.
