摘要

Using waste expanded polystyrene as the raw material, the azo polymeric dye (I-III) were prepared via nitration, reduction, diazotization and coupling reactions. The structures of the intermediate products and the polymeric dyes obtained were characterized by the FTIR spectra. By UV-Vis absorption spectrum measurements, the relationship among the maximum absorption wavelength, molecular structure and color of polymeric dye was investigated.
