Abstract
Mixtures of carbon disulfide and polystyrene with the composition 0, 5%, 20%, 40%, 60%, 80%, 100% by weight of CS2 have been studied using depolarized Rayleigh scattering experiments within the temperature range of 263–313 K. The spectral ranges between 20 and 150 cm−1 were described in the reduced representation by the 3-parameter-Mori-function, indicating that most of the spectral features depend more on the CS2 compound than on the polymer matrix. The concept of analyzing the line shapes of liquid systems by separating the logarithmic spectrum into various distinct regions with characteristic slope parameters was successfully applied to the CS2/polystyrene mixtures and indicates the existence of liquid CS2 microstructures in the mixtures and the applicability of the dipole-induced dipole mechanism to the investigated system.
