Abstract: The influences of a variety of external salts on the solution viscosity of sodium-cellulose sulfate half-ester were studied by viscometry method. The dependences of polymer conformation structure on salt concentration and cation as well as anion of salt were discussed seperately. The influences of polyvalent cation was also discussed simply.
