Some properties of polysulfone, chlorometylated polysulfone and quaternized polysulfone were studied by viscometry, interferometry and dialysis equilibrium. Modification of intrinsic viscosity, preferential and total adsorbtion coefficients explained the changes of the hydrodynamic dimensions with solvent quality. POLYM. ENG.
