AbstractA new method is proposed for extrapolating light‐scattering data to the zero angle of scattering. Essentially the method consists of iterative extrapolations by use of the regression method as a subroutine, and it applies in general to the data obtained at low polymer concentrations and at low angles of scattering. Light‐scattering results on high molecular weight linear polystyrene in benzene were successfully analysed with the method. In comparison with other published methods, the strong points and limitations of the method are discus
