Abstract

Under rigorously anhydrous conditions, no polyelectrolyte effects existed, Macromolecular sizes obtained from both techniques showed a linear dependence on M**1**/**3, indicating the macromolecules to be non-draining and spherical in shape. Comparison with calculated sizes indicates the molecules in solution to contain substantial amounts of solvent within their nondraining volumes. The ratio of radius of gyration to hydrodynamic radius, and shape analysis of some SAXS data, indicate that these spherical macromolecules may be somewhat less dense on the surface than their non-draining core. The results are in general agreement with previous results obtained by other techniques.
