Abstract
Cross-linked polystyrene is a kind of thermosetting plastic which has excellent dielectric properties and high breakdown voltage. In this paper, cross-linked polystyrene and polystyrene were analyzed by Fourier transform infrared spectroscopy (FTIR), and the reflective spectra were measured. Subsequent Kramers-Kronig analysis provided the dispersion of the refractive index and the absorption index across the infrared region. The results showed that the refractive index of cross-linked polystyrene decreased rapidly from 1.5 to 1.1 in the spectral region 100cm-1-4000cm-1, which was much lower than that of polystyrene (around 1.5).
