Polymer Coil

Temperature and concentration behaviour of the dynamic structure factor of poly(styrene) was measured in a marginal solvent (dibutyl phthalate) by quasielastic light scattering. Both the concentration and temperature dependences of the hydrodynamic radius of the polymer coil and of the hydrodynamic blob size were found to follow the scaling laws predicted by theory. A relation m + b = -1 between exponents m and b for the concentration and temperature dependence of the blob size in semidilute solutions has been derived, and its validity was checked experimentally.

The Continuum

AbstractA simple analytic expression for the first cumulant of the dynamic structure factor of a polymer coil in the Rouse model is derived. The obtained formula is exact within the usual assumption of the continuum distribution of beads along the chain. It reflects the contributions to the scattering of light or neutrons from both the internal motion of the polymer and its diffusion, and is valid in the whole region of the wave-vector change at the scattering.
