Hence, as follows from eqns [28], [31], and [33], analysis of small-angle scattering from dilute polymer solution enables one to evaluate both the g5uation radius (Rg) and the second virial coefficient of the coil-coil interaction A2.

The second virial coefficient A2 is determined from the concentration dependence of osmotic pressure [Eq. (1-76)] or scattered light intensity [Eq. (1.91)] from dilute polymer solutions. A2 is a direct measure of excluded volume interactions between pairs of chains.

SLS from Dilute Polymer Solutions The intensity iu.0(one) of light scattered by one isolated small isotropic particle being much smaller than the wavelength 2 of incident wnpolarized light of intensity Iq is given by Equation 3.12 ... 

Sufficiently dilute polymer solutions may be viewed as systems in which islands of polymer coils scattered in the sea of a liquid solvent occasionally impinge and interpenetrate. By this way, the spatial distribution of chain segments in them is quite heterogeneous and undergoes appreciable fluctuations from time to time. As the polymer concentration increases, the collision of the islands becomes more frequent and causes the chains to overlap and entangle in a complex fashion. 

A dilute polymer solution has a turbidity of 0.0100 cm . Assuming that the solute molecules are small compared to the wavelength of the incident light, calculate the ratio of the scattered to incident light intensities at 90° angle to the incident beam and 20 cm from 2 ml of solution. Assume that all the solution is irradiated. 

In Section 1.7.2, we will see that the weight-average molar mass can be measured by light scattering from a dilute polymer solution. The viscosity of polymer liquids correlates well with the weight-average molar mass. 

Scattering techniques for measuring various static and thermodynamic properties of polymers, such as molar mass, size, conformations, interaction parameters, etc. were described in experimental sections of Chapters 1-5. In addition to static properties, scattering can provide important information about dynamic properties of polymeric systems. This section focuses on dynamic scattering from dilute solutions, but similar methods are used in semidilute and concentrated solutions."...

We consider an experiment in which a monochromatic laser beam (with a frequency of the order of 10 s ) is incident into a small volume in a dilute polymer solution. Light scattered from that volume is received by a detector...
