Solution properties of sodium amylose sulfate (NaAS) in salt solutions have been studied by light scattering and viscometry techniques. The molecular weight is correlated with radius of gyration and second virial coefficient. The Mark‐Houwink relations have been established for the polymer in salt solutions of varying ionic strenth an at several temperatures. The applicability of the current solution theories has been discussed in light of the unperturbed dimensions. The stiffness parameters of the chains have been determined and compared with other polymers.
