  • Refractive index increments of polyacrylamide and

    The refractive index increments of polyacrylamide for various wavelength were determined both in the usual solvents (water, ethylene glycol, formamide) and in those so far unused (ethanolamine, dimethyl sulfoxide). The values thus obtained are compared with the reported data. The necessity to employ anhydrous polyacrylamide samples is stressed.
