Notes:
The refractive index increment of macromolecules in solution has been observed to be a function of concentration, temperature, molecular weight, wavelength of light, and solvent. Most of the studies have been performed in dilute or semidilute solutions, and therefore the concentration dependence of the refractive index increment was too small to be accurately observed. This study was performed on solutions of polystyrene in trans-decalin at mass fractions, w2, from 0.01 to 0.11 and at 436 and 546 nm wavelengths. The concentration and temperature dependence of the refractive index increment were measured, and comparisons were made with previous theories.
