Abstract
The conformational and dynamic behavior of fractionated samples of pullulan and dextran has been studied by means of static and dynamic light scattering. Measurements were carried out in water and in some θ solvents at various temperatures. Static light scattering yields the molar mass, M w , the radius of gyration, z 0.5 , and the second virial coefficient, A 2 . From dynamic light scattering we obtained the translational diffusion coefficient, D z,0 and the second hydrodynamic virial coefficient, k D,2
