A variety of powerful experimental techniques (oscillatory flow                 birefringence, oscillatory electric birefringence, dynamic light                scattering, forced Rayleigh scattering, small-angle neutron                     scattering, total intensity light scattering, and pulsed field                  gradient NMR) will be employed to provide a uniquely detailed and               comprehensive data set for at least one polymer/solvent system.                 Infinite-dilution properties (including coil radius,                            translational diffusion coefficient, intrinsic viscosity, longest               relaxation time, and relaxation-time spectrum) will be compared                 with the best available theories.  Simultaneous comparison of all               these properties will permit the most rigorous test of the                      strengths of molecular models, and in particular, evaluate the                  physical significance of parameter values.  In addition to the                  long-wavelength properties listed above, measurements of the                    local modes of relaxation available to the polymer and to the                   solvent will be made.  This will shed light on the hitherto                     unexplained high-frequency dynamics properties of polymer                       solutions, and provide the first systematic test of models for                  local polymer motions.  The ultimate goals include the                          development of techniques for enhanced polymer characterization                 and the elucidation of polymer structure-property relationships.
